xargs的不承认bash的别名 [英] xargs doesn't recognize bash aliases

问题描述

我试图运行下面的命令：

I'm trying to run the following command:

find . -iname '.#*' -print0 | xargs -0 -L 1 foobar

，其中foobar的是一个别名，或在我的.bashrc文件中定义函数（对我来说，这是一个函数，它接受一个参数）。显然xargs的不承认这些东西因为它可以运行。有一个聪明的办法来解决这个问题？

where "foobar" is an alias or function defined in my .bashrc file (in my case, it's a function that takes one parameter). Apparently xargs doesn't recognize these as things it can run. Is there a clever way to remedy this?

推荐答案

因为只有你的交互shell知道别名，为什么不只是运行的别名，而无需通过的xargs 分叉？

Since only your interactive shell knows about aliases, why not just run the alias without forking out through xargs?

find . -iname '.#*' -print0 | while read -r -d '' i; do foobar "$i"; done

如果您确信您的文件名没有在他们换行符（益，为什么他们会？），可以简化这

If you're sure that your filenames don't have newlines in them (ick, why would they?), you can simplify this to

find . -iname '.#*' -print | while read -r i; do foobar "$i"; done

甚至只是找到-iname'＃*。| ... ，因为默认目录为。键，默认操作是 -print

or even just find -iname '.#*' | ..., since the default directory is . and the default action is -print.

还有一个选择：

 IFS=$'\n'; for i in `find -iname '.#*'`; do foobar "$i"; done

告诉巴什说的话只在新行拆分（默认值： IFS = $'\\ t \\ n'）。你应该小心，虽然;某些脚本不应付好一个改变 $ IFS 。

telling Bash that words are only split on newlines (default: IFS=$' \t\n'). You should be careful with this, though; some scripts don't cope well with a changed $IFS.
