选项卡上的完整的bash变量扩展 [英] Bash variable expansion on tab complete
问题描述
我运行Ubuntu 11.04,和我看到一些奇怪的行为,当我试图与一个变量开始的路径上使用标签,完成在bash。如果我有TOP = /划伤,我尝试标签完成:
CD $ TOP /富
它更改为:
CD \\ $ TOP /富
我倒是preFER它完成于:
CD $ TOP / foobar的
要么
CD /刮/ foobar的
但我会满足于它只是不改变线路,并要求我未逃脱$。
有谁知道在bash / readline的我应该寻找解决这一问题?

的变通方法
尝试启用 direxpand
或 cdable_vars
:
禁用了javascript -s direxpand
# 要么
禁用了javascript -s cdable_vars
显然<一href=\"http://www.linuxquestions.org/questions/linux-general-1/bash-auto-complete-of-environment-variables-613203/#post3023856\">EscTab可能是一个解决办法:
我还没有找到这个合适的解决方案,但有一个变通方法。环境变量的转义可以通过pressing Esc后跟标签被禁用。
#$ CD + SO [Esc键] + [Tab]键
#$ CD SOME_DIR

I'm running Ubuntu 11.04, and I'm seeing some odd behaviour when I try to use tab-completion in bash on a path that starts with a variable. If I've got TOP=/scratch, and I try to tab-complete:
cd $TOP/foo
it changes to:
cd \$TOP/foo
I'd prefer it to complete to: cd $TOP/foobar or cd /scratch/foobar but I'd settle for it just not changing the line and requiring me to un-escape the $.
Does anyone know where in bash/readline I should look to fix this?

Workarounds
Try enabling
direxpand
orcdable_vars
:shopt -s direxpand # or shopt -s cdable_vars
Apparently EscTab might be a workaround:
I haven't found a proper solution to this, but there's a workaround. The escaping of environment variables can be disabled by pressing Esc followed by tab.
# cd $SO + [Esc] + [Tab] # cd $SOME_DIR
Confirm that as a bug! I just confirmed that the same thing works on
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 10.10 Release: 10.10 Codename: maverick
I get broken behaviour on (up-to-date) natty:
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 11.04 Release: 11.04 Codename: natty
Although I must add that I do not the slash escaped, but the path (while valid, existing, accessible and readable) is not getting expanded.
