LINUX - How to replace a string & its current value with a new value
Hi All,

i am trying to replace a string & its current value (P_JOBID =1000 for eg) in a file with a new value(P_JOBID =2000) through sed command.

File name : A.txt
Command I am trying :

Code:
`cat $path/A.txt | grep ${P_JOBID} | sed -e s/P_JOBID=/P_JOBID="$JobID"/g`

Output Expected : P_JOBID =2000

It is not working as expected as it is giving me output/error as follows,

Code:
Script.ksh: line 141: P_JOBID=10002000: command not found

Any thoughts will be very helpful.

Thanks,
Freddie

Remove the backticks. They serve no purpose.

Hi Corona,

Removing the backticks didnt help me resolve the issue. Any other thoughts.

Thanks,
Freddie

What did it do without the backticks, though?

Try:
Code:
oldid=1000 newid=2000
sed "s/P_JOBID=${oldid}/P_JOBID=${newid}/g" A.txt > A.new
