tcsh: var with current command

in tcsh !$ is the last argument of the last command line:

m:~> man find
m:~> echo !$
find

I'm searching a way to get the current command line (before entered)

m:~> echo $current_comm
echo

Thanks.

Solution

  • !# refers to the current command. It can be indexed by appending a : and a number.

    For example:

    % echo !#:0
echo echo
echo
%

    (The shell prints history expansions before executing them, which is why the echo echo line appears.)

    A more elaborate example:

    % echo arg1 arg2 arg3 COMMAND=!#:0 ARG1=!#:1 ARG2=!#:2 ARG3=!#:3
echo arg1 arg2 arg3 COMMAND=echo ARG1=arg1 ARG2=arg2 ARG3=arg3
arg1 arg2 arg3 COMMAND=echo ARG1=arg1 ARG2=arg2 ARG3=arg3
%
