macos - OSX 上的 sed 中有多个 '-e'

Question

我需要运行 sed -e 'command' -e 'command' file.txt 但我在 mac 上收到此错误:sed: -e: No such file or directory。知道如何解决这个问题吗？

Answer 1

适用于我的 sed:

$ echo ax | sed -e 's/a/b/' -e 's/x/y/'

$ uname -a

$ which sed
/usr/bin/sed

所以问题一定出在别处。根据您在评论中给出的命令判断，我会尝试将 '' 参数传递给 -i 选项:

$ sed -i '' -e "s/\.$REGIONID\./\./" -e "/\.$NONREGIONID\./d" application.conf

使用手册页中描述的警告:

If a zero-length extension is given, no backup will be saved. It is not recommended to give a zero-length extension when in-place editing files, as you risk corruption or partial content in situations where disk space is exhausted, etc.
