在包含“-”（连字符）的 shell 脚本中执行命令

Question

I want execute below command in shell script

CMD="/abc/def/ghi command1 command2 -p $VARIABLE --command3 true"

while executing this exec $CMD hyphen replacing with single quotes pasting debug output

+ exec '/abc/def/ghi command1 command2 ' 'p VALUE ' '' 'command3 true'

How to deal with it ?

Answer 1

Read I'm trying to put a command in a variable, but the complex cases always fail!

You want to use an array to store the command

cmd=(/abc/def/ghi command1 command2 -p "$variable" --command3 true)
exec "${cmd[@]}"

Or a function, but I'm not sure how to exec a function, unless you put it in the function

cmd() { exec /abc/def/ghi command1 command2 -p "$variable" --command3 true; }
cmd

Don't use ALL_CAPS_VARNAMES: leave those reserved for the shell.
