What are you actually trying to achieve? I can't work it out from what you have written.

You can do this using 'command substitution':
someVar=$(echo $value1 | sed 's/[()@.+/]/\\&/g')
Thank u.
i need one more help.
perl -pi -e 's/$c/$d/' test.txt
suppose i save the values in c and d variables. test.txt contains $c value.
i want to replace this value with $d value.
if i use this above command,it won't change.
what's the prob?can u pls help me?
Perhaps you should use double quotes rather than single quotes. The shell won't evaluate $c or $d if they're encased in single quotes.
Thanks.....
Hi,
if i use array, how can i replace it:
perl -pi -e "s/${d[$i]}/${b[$j]}" *.xml
if i execute, it shows
Substitution replacement not terminated at -e line 1.
Consult your previous perl command (post #6) to see how to properly terminate the substitution replacement.
