clipmenu is a simple clipboard manager using dmenu and xsel. Launch this
|
|
when you want to select a clip.
|
|
|
|
All arguments are passed through to dmenu itself.
|
|
|
|
Environment variables:
|
|
|
|
- $CM_LAUNCHER: specify a dmenu-compatible launcher (default: dmenu)
|
|
- $TMPDIR: specify the base directory to store the cache dir in (default: /tmp)
