Bash 中是否有任何 WORDCHARS 替代品？

Question

Conculusion:

• No WORDCHARS alternative in Bash, where Cw ends can't be configured.
• mysql depends on editline , which is customizable with ~/.editrc .
• redis-cli depends on linenoise , it deletes the whole word without considering : , -

---

In zsh, WORDCHARS controls the behavior of Cw when deleting a word. Is there any alternative in readline?

I've noticed recently the behavior of Cw in mysql / redis-cli differs that in Bash, although both of which depends on readline ?

Take string foo:bar as an example, only bar is deleted by Cw in Bash. While in mysql / redis-cli , the whole word foo:bar is deleted.

How do I control this behavior?

Answer 1

There are two commands to do backward kill word:

backward-kill-word
unix-word-rubout

backward-kill-word deletes bar , unix-word-rubout deletes foo:bar

Run following command to find out what Cw is bound to

bind -P | grep C-w

Seems bash doesn't have WORDCHARS as in zsh
