Globbing:
- ${VAR#pattern} :: delete shortest match from beginning
: file='sdf/fd' && echo ${file#sdf/}
- ${VAR##pattern} :: delete longest match from beginning
- ${VAR%pattern} :: delete shortest match from end
- ${VAR%%pattern} :: delete longest match from end
- ${VAR/search/replace} :: Regex replacement (kinda?)
Examples:
- ${VAR:*} :: retain the part before the last colon
- ${VAR##*/} :: retain the basename
- ${VAR%.*} :: remove extension
- [[https://unix.stackexchange.com/a/486694][argument from end of list]] ::
: eval last=\$$(($#-1))
(uses arithmetic substitution, a non-POSIX feature)
