我必须在 bash 脚本中运行一堆命令，并且我想回显当前正在运行的命令：
我有这个文件（大约 100 行）：
nohup command1 param1 param2
nohup command2 p1 p2
nohup cmd3 p1 p2 param3
我想：
echo "Running command1" ; nohup command1 param1 param2
echo "Running command2" ; nohup command2 p1 p2
echo "Running cmd3" ; nohup cmd3 p1 p2 param3
我试过 yank 但它一次复制 1 行，有没有办法复制所有行？
正则表达式是您在这里需要的：
:%s/^\(nohup\) \([a-zA-Z0-9]*\)/echo "Running \2"; \1 \2/
Why not just use sh set -x?
From bash(1):
-x After expanding each simple command, for command, case
command, select command, or arithmetic for command, dis-
play the expanded value of PS4, followed by the command
and its expanded arguments or associated word list.
你可以录制一个宏。
假设您在文件的第一个字符上，您应该键入：
`qa` "Start recording a macro into a
`w` "move to first word following nohup
`yiw` "copy the word under cursor
`^` "move cursor back to beginning of line
`i` " enter insert mode
`echo "Runnning<ESC>pi";<ESC>` "paste the previously copied word
`j` " go down one line
`^` "move cursor back to beginning of line
`q` " stop recording the macro
`@a` " rexecute macro on second line
如果这按预期工作，键入98@@应该调用最后一个宏 98 次并格式化您的文件。
