Pattern matching and word substitution

[Guest_imported]

Hello,
Does anyone know how to modify certain words in a file. Like for example replacing the word Variable by 100. For example, the it is in the form <TAG>Variable<\TAG>.
Please advice.
Thanks,
GTFY

Hi,

you can use sed command like this :
VAR=100
VAR2=102
sed -e &quot;s%variable%$VAR%&quot; -e &quot;s%variable2%$VAR2%&quot; file

Regards.

Hi GTFY!

You can also use awk to do this job:

awk "/TAG/ { gsub(/Variable/,100) } { print }" file.xml

This code changes each line of file.xml that contains string 'TAG'.

Even better regular expression is /<TAG>/ (or /\<TAG\>/).

Bye!
