I have symlinks in a directory full of versions that each point to a specific version.
The file structure would look like this:
- /path/to/stuff/v1
- /path/to/stuff/v1.1
- /path/to/stuff/v2
- /path/to/stuff/v3
- /path/to/stuff/A -> /path/to/stuff/v1.1
- /path/to/stuff/B -> /path/to/stuff/v3
I need a way to get only the version number from a specific symlink (i.e for /path/to/stuff/A I want only "v1.1").
readlink gets the whole path: readlink /path/to/stuff/A = /path/to/stuff/v1.1
I’ve scoured other questions but nothing I’ve found has met these exact requirements yet
>Solution :
You can either use basename with command
substitution (available in all POSIX shells, not only in Bash):
$ basename "$(readlink /path/to/stuff/A)"
v1.1
Or rev + cut:
$ readlink /path/to/stuff/A | rev | cut -d/ -f1 | rev
v1.1
