I have a bunch of files with different extensions and i would like to add a suffix at the end of all of their names:
Fe2-K-D4.rac Fe2-K-D4.plo Fe2-K-D4_iso.xy ... to
Fe2-K-D4-4cc8.rac Fe2-K-D4-4cc8.plo Fe2-K-D4-4cc8_iso.xy ... I read a few posts about changing the extension using the rename tool but i don't know how to change the name and keep the same extension (I'm a recent linus user).
Thanks for any help
Using Extract filename and extension in Bash, I would say:
for file in * do extension="${file##*.}" filename="${file%.*}" mv "$file" "${filename}-4cc8.${extension}" done This loops through all the files, gets its name and extension and then moves it (that is, renames it) to the given name with an extra -4cc8 value before the extension.
Using rename:
rename 's/[.]([^.]+)$/-4cc8.$1/' * s/[.]([^.]+)$/-4cc8.$1/ is a perl expression of the form s/PATTERN/REPLACEMENT/ which tells rename to do a global substition.
[.]([^.]+)$ is a regex pattern with the following meaning:
[.] match a literal period ( followed by a group [ containing a character class ^. composed of anything except a literal period ]+ match 1-or-more characters from the character class ) end group $ match the end of the string. The replacement pattern, -4cc8.$1, tells rename to replace the matched text with a literal -4cc8. followed by text in the first group matched, i.e. whatever followed the literal period.
