After Ubuntu 22.04 installation, just little problem with save dialog.

Example, in case of save file in web browser (chrome), save dialog is maximized and not active, so I must click on it and then save dialog is active.

In past, it was active immedietelly without clicking, so in case of save file, I can write name of file without click.

Maybe problem is maximized window of save dialog? But I don't know how to "normalize" this window.

Thanks for help.

I have 3 source files.

1.txt - template.

<field name="COL1" label="COL2" data-source="COL1" classes="attribute" category="Attribute"/>

2.txt - variables for COL1.

IDNName
BusinessUnit
WWB
IncentiveID

3.txt - variables for COL2.

IDN Name
Business Unit
WWB
Incentive ID

I need output like this (take 1st line from 2.txt and 3.txt and insert to template, then take 2nd line from 2.txt and 3.txt and insert to template, etc...)

<field name="IDNName" label="IDN Name" data-source="IDNName" classes="attribute" category="Attribute"/>
<field name="BusinessUnit" label="Business Unit" data-source="BusinessUnit" classes="attribute" category="Attribute"/>
<field name="WWB" label="COL2" data-source="WWB" classes="attribute" category="Attribute"/>
<field name="IncentiveID" label="Incentive ID" data-source="IncentiveID" classes="attribute" category="Attribute"/>

Is possible to do it by one for condition with sed? I tried, but I don't know how to combine 2 files in one row.

for i in $(cat 2.txt); do cat 1.txt | sed 's/COL1/'$i'/g'; echo; done

Thanks.

I need "set" variable from script to memory (global) and read it again in second run of this script with defined last state of this variable.

Script.

echo $count
let "count=count+1"
export $count
echo $count

This shows me 1 when I run this script again. I need 1, and in the case I run the script again, I need 2, in case of third run 3, etc.

I thought export do this, but it is not working.

Thanks.

I have this script to compare cpuload is greater then limit 10.

#!/bin/bash

cpuload=$(uptime | cut -d' ' -f 13 | sed '$ s/.$//')
limit=10

echo
echo "cpuload = $cpuload, limit = $limit"
echo

[[ $cpuload > $limit ]] && echo | mail -s "cpuload $cpuload is higher than $limit!" EMAIL

Now, I am receiving emails even if value is lower than limit (3 > 10).

Where is the problem?

I tried combinations with condition syntax, but sometimes it is working, sometimes not... I am little confused.

Thanks.

UPDATE

cpu_load=$(uptime | cut -d' ' -f 13 | sed '$ s/.$//')
limit=1

send_email(){
echo | mail -s "makroczsk, cpuload $cpu_load is higher than limit $limit!" $email_to
}

echo "cpuload = $cpu_load (${cpu_load%%.*}), limit = $limit"

[[ (( ${cpu_load%%.*} > $limit )) ]] && send_email
[[ ${cpu_load%%.*} -gt $limit ]] && send_email

cpuload = 3.10, limit = 10
./check-cpuload.sh: line 9: [[: 3.10: syntax error: invalid arithmetic operator (error token is ".10")

And in 1st case, emails are still coming.

UPDATE 2

This works. But I am not sure why. :/

cpu_load=$(uptime | cut -d' ' -f 13 | sed '$ s/.$//')
limit=1

send_email(){
echo | mail -s "makroczsk, cpuload $cpu_load is higher than limit $limit!" $email_to
}

echo "cpuload = $cpu_load (${cpu_load%%.*}), limit = $limit"

#[[ (( ${cpu_load%%.*} > $limit )) ]] && send_email
[[ ${cpu_load%%.*} -gt $limit ]] && send_email

I have problem in DBeaver with russian (azbuka) chars. Everything was fine, but now I see this.

It is on OS level or it is app related? How can I fix it? OS Ubuntu 20.04.

Thank you.

Voice feature (mic) in google translate is not working in chromium. When I clicked on mic button, record looks like it started, but after 0.5 second it stopped.

Version 80.0.3987.87 (Official Build) Built on Ubuntu , running on Ubuntu 18.04 (64-bit)

And question, is there some plugin for chromium or app for Ubuntu? For translation online based on incoming voice stream, for example when you call on hangouts.

Thanks.

Is possible to setup CPU load or RAM for better multitasking? Because when I for example copy files or tar/untar some bigger file, OS is terribly slow due this operation.

Thanks.

OS Ubuntu 18.04.

HW CPU i7, 8GB RAM, SSD.

Update

When tar zxvf SOME_BIG_FILE.tar.gz (file about 3GB), due this process is not possible to work, switching between windows with ALT+TAB takes 2 seconds, keyboard and mouse get stucked in 5 seconds interval.

CPU is not so high (sometimes some process takes me more and all is ok).

I suppose this is some disk process related? Or how can I find out brownie?

Is it possible to change background color, transparency and font family in Dash to Panel? I was searching, but no success.

OS Ubuntu 18.04.4.

Update

Followed links in comment, but no success. I am using gnome-shell-extension-dash-to-panel tweak extension. Is it working with that?

I have this script:

date_time=`date "+%Y%m%d%H%M%S"`
script_name=`basename "$0"`

echo $date_time, $script_name
sleep 2
echo $date_time, $script_name
exit 1

It shows me this (same time).

20200103114357, clone.sh
20200103114357, clone.sh

I need date and time when I call the variable as command. There are 2 seconds between next time, but time is the same. How can I do that? Thanks.

Issue, I tried setup and connect to VPN with SecurID, but nothing happened.

I have this information about VPN.

authentication method: SecurID; SecurID authentication: PinPad

Question, is possible connect to this VPN from linux ubuntu? Do I need some extra configuration file? Is my configuration and vpn configured correctly? Could I use configuration file from MAC (*.sdtid) on linux for VPN connect (or this file is only for generating token)? What kind of VPN should I use?

And about token, I am getting it from app on Android (SecurID), but I tried stoken for Ubuntu, but this app generate 8 digits, but I Android app generate only 6 digits (it works). Where could be the problem?

Just note, that on Win or MAC is this application needed for connection to VPN. Is this Cisco AnyConnect as the VPN client? Can I use network-manager-openvpn-gnome?

In xfce, where can I change (set path for) icons for Window buttons plugin, and change resolution? Quite big now in panel, I want them smallest, same as in Notification area (2 last icons on the righ side).

How exactly icon works in xfce 4.12? Is it better in version 4.14?

Thanks.

Issue

How can I store whole line output from grep as 1 variable, not for every string.

Example (I need just 3 variables, whole lines).

user@local:~/bin/kb$ grep -E '##.*bash.*file.*add' bash.kb
## bash, file, add string behind founded string
## bash, files, add string to begin
## bash, file, add comma to end of line except last line
user@local:~/bin/kb$

But for example.

user@local:~/bin/kb$ for i in $(grep -E '##.*bash.*file.*add' bash.kb); do echo $i; done
##
bash,
file,
add
string
behind
founded
string
##
bash,
files,
add
string
to
begin
##
bash,
file,
add
comma
to
end
of
line
except
last
line
user@local:~/bin/kb$ 

I need this (only 3 variables as whole line).

1st variable $i[0] = '## bash, file, add string behind founded string'
2nd variable $i[1] = '## bash, files, add string to begin'
3rd variable $i[2] = '## bash, file, add comma to end of line except last line'

How can I do that?

Thanks.

How can I remove rest of file from string for all files?

For example, input files 1 and 2, string is ddd.

Input file 1.

aaa
bbb
ccc
ddfbbd dddaaa
eee

Output file 1.

aaa
bbb
ccc
ddfbbd 

Input file 2.

ccc
aergddd
dasdvsdb

Output file 2.

ccc
aerg

Issue

In bash, output is on 1 line from command, so <pre> is not working in html tag.

log=`cat ../local/log/$(ls -t ../local/log | head -1 )`
echo '
    <tr style="background-color: rgb(250,240,240);">
    <td style="padding: 10px; text-align: center;"><pre>'$log'</pre></td>
    </tr>
' > itf-check-article.html

How can I do get output to variable as classic line by line, not in one line?

Thanks.

Update.

Command.

log=`cat ../local/log/$(ls -t ../local/log | head -1 )`; echo $log.

Output (1 line).

Start of processing orders. 0 order(s) in this run. No orders in this run

But this command shows me this (with 2 lines).

itfstage@vm14258:~/sofimon$ cat ../local/log/UNIHOBBY_ITF_ORDERS.log

VID_20190420_130214.3gp  
VID_20190420_141700.3gp  

And I want to concatenate 3GP files by a script (perhaps with ffmpeg ?) into one file, selecting files by the YYYYMMDD date in the file name, with a result of:

VID_20190407.3gp
VID_20190415.3gp
VID_20190420.3gp

What is the best way to script that?

How should I configure multiple virtual hosts with a single configuration file in Apache using ssl with redirecting?

What is needed and not needed in my configuration below? Is possible for example set Include /etc/letsencrypt/options-ssl-apache.conf SSLCertificateFile /etc/letsencrypt/live/hosek/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/hosek/privkey.pem to begin of file only? For all vhosts?

Is possible to make whole configuration to one file, especially one VirtualHost? I have 2 files now, one for 80, second for 443.

Example of my vhosts.

no-ssl.conffile.

<VirtualHost *:80>
ServerName www.thehatmakers.cz
ServerAlias thehatmakers.cz

</VirtualHost>

Thanks.

Update

If not possible to do with 1 VirtualHost, what about this configuration? Is any shorter way to do this? Is possible to use Redirect for ssl? As I have commented for *:443 configuration? Can I use Include /etc/letsencrypt/options-ssl-apache.conf SSLCertificateFile /etc/letsencrypt/live/hosek/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/hosek/privkey.pem outside VirtualHost configuration? And what about google, is it ok with this redirecting? I am using 1 certificate for all domains, is it ok?

<VirtualHost *:80>
ServerName www.thehatmakers.cz
ServerAlias thehatmakers.cz
Redirect / https://www.thehatmakers.cz
</VirtualHost>

<VirtualHost *:443>
ServerName www.thehatmakers.cz
ServerAlias thehatmakers.cz
#Redirect / https://www.thehatmakers.cz
RewriteCond %{HTTP_HOST} ^(thehatmakers.cz) [NC]
RewriteRule ^(.*)$ https://www.thehatmakers.cz$1 [R=301,L]
DocumentRoot /var/www/html/thehatmakers
Include /etc/letsencrypt/options-ssl-apache.conf

Issue

I need to get output as commands, in a bash script, for storing variables.

Example

sed -n '/# Main configuration./,/# Websites./p' webcheck-$category.cfg | sed '1,1d' | sed '$ d'

This command returns these lines:

email_sender='[email protected]'
email_recipients='[email protected]'

How can I read/run these output/lines as commands in script? Is storing this output to the file and then read it by source command only way?

I tried | source at the end of the command, but it reads only from files.

I tried echo at the beginning, but that had no effect.

Thanks.
