Linux red hat + replace PATH or word on scripts

Question

Under folder:

/var/userTN/applo folder

I have around ~100 shell scripts that include the following PATH:

GLOBAL_PATH=/export/pop/PLW5

I want to replace the PATH on all the scripts under folder:

/var/userTN/applo 

to this PATH

GLOBAL_PATH=/export/lld/sat

How to replace the PATH:

GLOBAL_PATH=/export/pop/PLW5

On all the files under folder:

/var/userTN/applo

With find + sed or other approach ? ( as Perl one liner solution )

remark:

Replace should be match exactly the “GLOBAL_PATH=/export/pop/PLW5”

For example

The PATH -> GLOBAL_PATH=/export/pop/PLW51 ( should not replaced! )

Answer 1

Using sed:

sed -i.bak 's#^\(GLOBAL_PATH=/export/\)pop/PLW5$#\1lld/sat#' /var/userTN/applo/*

The original file(s) will be backup up with .bak extension, if you don't want backup(s):

sed -i 's#^\(GLOBAL_PATH=/export/\)pop/PLW5$#\1lld/sat#' /var/userTN/applo/*

Example:

$ sed 's#^\(GLOBAL_PATH=/export/\)pop/PLW5$#\1lld/sat#' <<<'GLOBAL_PATH=/export/pop/PLW5'
GLOBAL_PATH=/export/lld/sat
