Rename multiple files based on pattern in Unix
There are several ways, but using rename will probably be the easiest.
Using one version of rename:
rename 's/^fgh/jkl/' fgh*Using another version of rename (same as Judy2K's answer):
rename fgh jkl fgh*You should check your platform's man page to see which of the above applies.
This is how sed and mv can be used together to do rename:
for f in fgh*; do mv "$f" $(echo "$f" | sed 's/^fgh/jkl/g'); doneAs per comment below, if the file names have spaces in them, quotes may need to surround the sub-function that returns the name to move the files to:
for f in fgh*; do mv "$f" "$(echo $f | sed 's/^fgh/jkl/g')"; done
rename might not be in every system. so if you don't have it, use the shellthis example in bash shell
for f in fgh*; do mv "$f" "${f/fgh/xxx}";done
