calling comman from history using variable like : !$command

dale_chip · 11-19-2008, 02:19 AM

suppose i store the history number of a command say :
1004 cat file

Then now i want to run it like : !1004 but by using a variable.
command=1004
!$command

i am getting errors like :
command=1004command

can it be done ?
Thanks in advance

That won't work because "!$" is the last argument of the last command line.

Code:

fc -s $command $command

should work, however.

Thank you very much.

But i have also enabled shopt -s histverify
so that commands from history do not get executed but come on the current line buffer.

but in this case its getting executed right away.
if it could be paused in someway , it'l be great.
