Aigles, ran your solution:
Code:
sed -n '/the_string/{s/the_string//2;t;p;}' inputfile

And received an error message:
Code:
Too many {'s

This command works fine with GNU sed.
I tried the command on my AIX box, and i get the same error than you.
The t sub-command of sed interprets all that follows as being a label.

The following syntax is accepted on AIX :
Code:
sed -n -e '/the_string/{s/the_string//2;t' -e 'p;}' inputfile

Welcome to the forums Smilie

This is not encouraged.

As a start looking for something like this,
Code:
val=`echo "orderlink=20" | sed 's/^.*=//g'`



Actually this should have been a new thread Smilie

If searchstring is "string"
