# Limited and very hacky wildcard rename # works for rename *.ext *.other # and for rename file.* other.* # but fails for rename file*ext other*other and many more # Might be good to merge this technique with mmv command... mv-helper() { argv="`history 1 | perl -pe 's/^ *[0-9]+ +[^ ]+ //'`" files="`echo \"$argv\"|sed -e \"s/ .*//\"`" str="`history 1 | perl -pe 's/^ *[0-9]+ +[^ ]+ //' | tr -d \*`" set -- $str for file in $files do echo mv $file `echo $file|sed -e "s/$1/$2/"` mv $file `echo $file|sed -e "s/$1/$2/"` done } alias rename='mv-helper #'
