: 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
