I've tried this solution to prevent duplicate cronjob from running.
30,31 12 * * * /usr/bin/flock -n /tmp/my.lockfile ~/Desktop/test.sh >> ~/Desktop/test.log 2>&1
and script test.sh has
#!/bin/bash
for i in {1..40};do
echo "hello$i"
sleep 2
done
Script test.sh successfully prevented from running at 12:31 but it stops and I want to resume it. How can I make it only suspend, not stopped and resume back? Is it possible?
I'm trying to install ADE in Ubuntu 16.04 32 bit.
First I run: wine ~/Downloads/ADE_4.5_Installer.exe but got an error
Second, I tried to install with winetricks, go to install an application option and select Adobe Digital Editions 4.5 and at the end, it shows the error.
In both methods, it shows the same error:
Program Error Detail shows:

I have a simple script to print color text in terminal which I've directed to log file too.
#!/bin/bash
echo -e "\033[01;32mGreen color" > ~/Desktop/color.log
When I run from terminal cat color.log, it prints with green color but when I open file with gedit it shows as
[01;32mGreen color
Is it possible to redirect with color in gedit?
I have hard disk which is not detected in bios and also in disk utility.
I've tried to mount in another system, still same issue and also tried to mount in Windows still same issue. I've used ddrescue in past but it was in case where hard drive was detected.
How can I recover data in this case?
I have a filename @! in my home folder. When I open it, it has the same content that my other bash file myscript.sh has.
I have not assign execute permission to original bash file. When I have checked properties, the only difference between two file is size. Original file size is 1.1 KB and @! file size is 714 bytes. How is it automatically created?
My system stuck at ubuntu logo while booting. To resolve it, I've set nomodeset.
But now it occurs a resolution issue to 1024x768. Here are the necessary information:

I've tried solution 1 and solution 2 but no success.
This issue occurred only after installing it, not when I choose 'Try without Installing', I don't need to set nomodeset in that case.

I've installed xserver-xorg-video-intelandxorg-dev. I've tried acpi_osi=linux,acpi_backlight=vendor, noalpic, i915.modeset=0 also create xorg.conf file and modify file /etc/initramfs-tools/modules to add i915 and intel_agp drivers as mentioned here.
I'm using following command to transfer file using rsync to only one connected host:
rsync -az -e ssh /path/to/source 192.168.8.8:/path/to/destination
This is the case of static ip addesss. But in other case there are more than one system connected using DHCP.
I've tried:
rsync -az -e ssh /path/to/source 192.168.8.*:/path/to/destination
But it shows an error
ssh: could not resolve the hostname 192.168.8.*: Name or service not known
When i run command:
ssh user@host "zenity --warning --width=500 --no-wrap --text="Your $VPN is not connected. Please connect it or inform to engineer" --display=:0"
If I use single quote then it works fine but there is a variable so I had to use double quote and It display like:
For example, if i run df -h
Filesystem Size Used Avail Use% Mounted on
udev 985M 0 985M 0% /dev
tmpfs 201M 9.1M 192M 5% /run
/dev/sdb3 87G 26G 57G 31% /
tmpfs 1003M 15M 989M 2% /dev/shm
tmpfs 5.0M 4.0K 5.0M 1% /run/lock
tmpfs 1003M 0 1003M 0% /sys/fs/cgroup
From its output if i want to print a line
/dev/sdb3 87G 26G 57G 31% /
that contain root partition /.
Then How to do it with awk?
I do not want to use /dev/sdb3 in search pattern. In search pattern, use only /.
I've tried answer posted on Stackoverflow but it did not work.
I'm trying to differentiate these four terms login, non-login, interactive and non-interactive:
As I understand
interactive - non login shell: Start the system, log in to system and open terminal and
non-interactive - login shell: telnet to system and log in
But what about an interactive - login shell?
Does it log in to the system, open virtual terminal and log in? and
non-interactive - non-login shell, is it running automated script in crontab?
I was learning about Common shell programs.
When I run cat /etc/shells, it shows:
# /etc/shells: valid login shells
/bin/sh
/bin/dash
/bin/bash
/bin/rbash
What is /bin/rbash here? Is it used in scripting?

I'm using Ubuntu 16.04
I want to open multiple terminal tabs, run commands and set title. I can open multiple tabs with this command:
gnome-terminal --tab -e "command1" --tab -e "command2"
but cannot use --title option as it is not available in this version.
I know mate-terminal can do this, but I want to use gnome-terminal.
I've applied solution posted here and it worked but when i run
gnome-terminal --tab -e "bash -c 'set-title 99;ping 192.168.7.99'"
It shows:
bash: set-title: command not found
PING 192.168.7.99 (192.168.7.99) 56(84) bytes of data.
64 bytes from 192.168.7.99: icmp_seq=1 ttl=128 time=0.425 ms

64 bytes from 192.168.7.99: icmp_seq=3 ttl=128 time=0.335 ms
I also applied the solution suggested here on Unix & Linux SE
I've also read this post setting-terminal-tab-titles but the accepted answer did not solve my issue in 16.04 os or gnome-terminal version 3.18.3 and other solution provides to use other terminal xterm and I want to use gnome-terminal.
I created a simple desktop file to check the connectivity of remote location in which Exec=ping 192.168.0.9. But one file created with #!/usr/bin/env xdg-open before Desktop Entry and another without #!/usr/bin/env xdg-open and both worked the same. Then What is the use of it in desktop file? What does it mean?
I know that packages installed with apt-get are stored in /var/cache/apt/archives.
I just installed mariadb server in Ubuntu 16.04 with following command:
sudo apt install mariadb-server
When I tried to find packages in /var/cache/apt/archives, there are no packages. Where are they stored if it's not in this directory?
Completely confused with this new feature snap. I know this might be detailed question-answer but I need to know some info regarding it.
I have read that new application format, snap which can be installed by default in the latest long-term support release alongside traditional deb packages. So, Does it mean are there packages with .snap extension like .deb? Then, How to install?
The user can use newer versions of apps on older versions of Ubuntu without forsaking the stability of your entire system. Is this the only difference between deb and snap? Does it only exist to LTS version or for non-LTS too?
With this, it is also said that Creating snaps is simplified for developers with the introduction of a new tool called “snapcraft” to easily build and package applications from source and existing deb packages. Is it useful to desktop user or only for developers ?
I don't have much knowledge of shell scripting. I have a command which is used multiple times but value is modifying.
Here is my script:
#!/bin/bash
tab=" --tab-with-profile=Default"
options=(--tab --title=Terminal)
cmd[1]="ping 192.168.9.10"
title[1]="10"
cmd[2]="ping 192.168.9.20"
title[2]="20"
cmd[3]="ping 192.168.9.30"
title[3]="30"
cmd[4]="ping 192.168.9.23"
title[4]="23"
cmd[5]="ping 192.168.9.26"
title[5]="26"
cmd[6]="ping 192.168.9.40"
title[6]="40"
cmd[7]="ping 192.168.9.41"
title[7]="41"
cmd[8]="ping 192.168.9.42"
title[8]="42"
cmd[9]="ping 192.168.0.43"
title[9]="43"
cmd[10]="ping 192.168.9.50"
title[10]="50"
cmd[11]="ping 192.168.9.11"
title[11]="11"
cmd[12]="ping 192.168.9.12"
title[12]="12"
for i in 1 2 3 4 5 6 7 8 9 10 11 12; do
options+=($tab --title="${title[i]}" -e "bash -c \"${cmd[i]} ; bash\"" )
done
gnome-terminal "${options[@]}"
exit 0
I don't want to write cmd[i] and title[i]for multiple times. I want to write one single command that execute it multiple times.I don't know how to use for or while loop and execute a single command for different process rather multiple times.
I am transferring file to Windows server from Ubuntu with following command:
smbclient //server_ip_add/share -U username
We can use rsync to transfer file from Ubuntu to Ubuntu and then by creating script run it as cronjob. Is it possible to do all this from Ubuntu to Windows?
I know this may possibly a duplicate but i tried a lot of things to solve this error. There are already two partition and i am trying to create third one
but it shows the following error.
Even i formatted pendrive completely still it shows this error. it happens on ubuntu 14.10 . How to solve it?
Is it possible to connect remote system using mac-address in Ubuntu? I don't want to use IP address. Both systems are in same LAN.
