coolcommand
one-liner to do a search and replace in a file |
Description
Here is a quick one-liner which performs a search and replace of a regular expression in the same file where it finds the match. It is a combination of the find command and perl:
Example to do a search and replace of first occurance of match in the file site.conf:
# find . -name "site.conf" -exec perl -i -p -e "s/csc2.tar.gz/csc3.tar.gz/" {} \;
Example to do a search and replace of all matches in the file site.conf:
# find . -name "site.conf" -exec perl -i -p -e "s/csc2.tar.gz/csc3.tar.gz/g" {} \;
Example to do a search and replace for any files which end with a .pl extension:
# find . -name "*.pl" -exec perl -i -p -e "s/old_string/new_string/g" {} \; |
Example
find . -name "*.pl" -exec perl -i -p -e "s/old_string/new_string/g" {} \; |
