Search and Replace across multiple files
Most of us stuck at some point of time to replace a string in multiple files.
How do we do this? Write a few lines of code to do this job (or possibly a script). We have got perl to help us out to do this same task in single line..# perl -pi -i.orig -e 's/scalar/vector/g' *.xml
If we fire this CLI in current directory then it will replace all occurrences of word ‘scalar’ to ‘vector’ in all .xml files while backing up all original ‘files.xml’ file and renaming them to ‘files.xml.orig’.

ReplyDeleteThis will be very useful in day to day work.
ReplyDeletewill this work in windows ??
ReplyDeleteIt works on Unices but not sure on windows. Limitation may be the wildcards that can be accepted by perl CLI.
ReplyDeleteWhen I tried then I received following message,
c:\>perl -pi -i*.orig -e 's/scalar/vector/g' *.xml
Can't open *.xml: Invalid argument.
However, exclusion of wild card such as following CLI works perfectly.
c:\>perl -pi -i*.orig -e 's/scalar/vector/g' test.xml
For windows, you can try using tool called http://www.wingrep.com/download.htm (WinGrep). It will help you to search and replace across multiple files
