-Hi, I have several hundred files, which contain the following pattern:
/bb/bin/msga/mm 80&
I need to change the above pattern to be
/bb/bin/mm 80&
I there the command I can use to do that. Thanks a lot

for file in `grep -R '/bb/bin/msga/mm' .`; do perl -p -i.bak -e 's:/bb/bin/msga/mm:/bb/bin/mm:' "$file"; done

Or just :

sed "s/msga\///" <file

Hi, another view, and a question; are all the files You want to change in the same directory? Then You could try something like

Code:

sed -i.bak -e "s_/bb/bin/msga/mm 80\&_/bb/bin/mm 80\&_g" *

the -i.bak saves the original with a bak-extension just in case.
