[ale] history command in script



Yeh, you right. Another good way to do it is to insert it right into the
interactive shell as part of the environment. I tried this and it worked
fahn:

nameOfScript () {

echo "Do you want the full argument or just the base command?"
read answer


if echo $answer | grep -i y ; then
   history 1000 | tr -s " " | cut -d " " -f3- | sort | uniq -c |sort -r
| less
else
   history 1000 | cut -d' ' -f5 | sort | uniq -c | sort -r | less
fi
}

You can then invoke this by typing "nameOfScript".
The easy  way to do this is to create a script file with the above lines
in it,
->DON'T<- chmod +x  it, and run it from the ".". Leaving it
non-executable is to remind 
you not to run it by typing its name, which will simply create a
subshell containing the command which then immediately exits. 

Most k00l HAX04 D00Ds already have a "${HOME}/.envfile" for stuff like
this, which they run from the dot in their profile scripts. If you set
the "BASH_ENV" symbol to the envfile filename, then it will
automagically run for any sub-shells you spawn, so your routines are
available all the time.

        R'ing TFM, it looks like the `history' builtin isn't enabled
by default in non-interactive shells.  Look for the part about the
`set' command, specifically the part under `-o option-name'.  It
probably would work if you added `set -o history' before trying to
call the history command.
