Problem in calling a script inside a script
Hi team,

I have a script in different folder. Now i want to call that script and execute that script from that path alone.

My code is
HTML Code:
#!/bin/bash
wname=yahoo
PATH='/opt/IBM'
wac=`/usr/bin/ls $PATH | /usr/bin/grep "$wname"`
STOP=`/usr/bin/find $PATH/$wac -type f -name "stop.sh"`
/usr/bin/sh $STOP & (here i am executing the script in background)
/usr/bin/sleep 5 
kill  (after 5 sec it need to kill the sleep process)

$! holds the PID of the last background process that was executed

Best is to use another variable name instead of PATH.PATH is a system variable and may cause issues when using otherway.
And you need not to give "&" for background process.You may call the main script in background as well

Off topic: The $PATH environment variable is reserved for the Shell. Choose another name for your environment variable ... $SEARCH ?

If you overwrite $PATH in the manner of your script, the Shell will not be able to find any command (ls / find / grep ... whatever) from that point on.

Not sure what's a file and what's a directory in your script and whether the string "yahoo" is the full name or part of the name of something.

What is the output from this enquiry:
Code:
file `ls /opt/IBM | grep "yahoo"`

Does the path to stop.sh ever change?

Are you sure there will always only a single stop.sh be found?

o/p of that command is
/opt/IBM/yahoo/stop.sh
