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.
