I have made a bash command which generates a one liner for restarting all Weblogic ( 8,9,10) instances on a server. The script works well but I need a suggestion to make it better using the dirname concept

/usr/ucb/ps auwwx | grep weblogic | tr ' ' '\n' | grep security.policy | grep domain | awk -F'=' '{print $2}' | sed 's/weblogic.policy//' | sed 's/security\///' | sort | sed 's/^/cd /' | sed 's/$/ ; cd .. ; \/recycle_script_directory_path\/recycle/ ;'  | tr '\n' ' '

To restart a Weblogic instance, the recycle ( /recycle_script_directory_path/recycle/) script needs to be initiated from within the domain directory as the recycle script pulls some application information from some .ini files in the domain directory.

The following part of the script generates a line to cd to the parent directory of the app i.e. the domain directory

sed 's/$/ ; cd .. ; \/recycle_script_directory\/recycle/ ;'  | tr '\n' ' '

I am sure there is a better way to cd to the parent directory like cd dirname but every time i run the following cd dirname command , it throws a "Variable syntax" error.

cd $(dirname '/domain_directory_path/app_name')

How do i incorporate the cd dirname in my bash command ?

Please let me know if there are any more enhancements I can do

Some info on my script

1) The following part lists out the weblogic instances running along with their full path

/usr/ucb/ps auwwx | grep weblogic | tr ' ' '\n' | grep security.policy | grep domain | awk -F'=' '{print $2}' | sed 's/weblogic.policy//' | sed 's/security\///' | sort

2) The grep domain part is required since all domain names have domain as the suffix

I need to run a custom script which runs when Windows boots up.I know its possible to run it when a user logs in but I want to run it when the system reboots i.e. prior to a user logging in. The OS in question is Windows 2003 and Windows 2000

I have an expect script which checks if a file exists on a remote server and then tries to print ( using cat) it if it does

For some reason the expect script ignores these commands.

send "if {[file exists "./abc.test"]} {cat ./abc.txt\r}"

My Script throws the error read error: 0: Resource temporarily unavailable the second time user input ( Unix Username ) is expected.

I suspect this has something to do with the first background process (linux_fetch &) going wrong.

How do I work around this so that the user prompt ( Unix Username ) post the background process does not get affected.

Here is short snippet of the script.

if [ -r $linux_host_list ]
then
    echo
    read -p 'Linux Username:' LUSERNAME
    read -p 'Linux Password:' LPASS
    linux_fetch &
    clear screen
else
    echo "No Linux Servers found"
fi

if [ -r $unix_host_list ]
then
    echo
    read -p 'Unix Username:' UNIXUNAME
    read -p 'Unix Password:' UPASS
    unix_fetch &
    clear screen
else
    echo "No Unix Servers found."
fi
