[gentoo-user] locate

Just recently tried using

locate foo.conf | cd

to automagically move to the directory in which I've saved foo.conf
Of course it didn't work as you can't cd to /bar/foo.conf

I didn't find a way to dropping the actual file name from the result of
locate.
I did a brief google on locate, but didn't find a switch to drop the actual
file name from the result.

Can it be done, or if not what should I use to get the desired result?

Martin S

cd $(dirname $(locate foo.conf))

It would not have worked anyway, since cd does not read its input from 
stdin. Try:

[/]$ echo "etc" | cd
-bash: echo: write error: Broken pipe
[/]$

It's not a locate problem. Use the "dirname" command.

$ dirname /bar/foo.conf
/bar
$

and do something like

cd $(dirname "$(locate foo.conf)")

of course, make sure that the locate command returns just a single entry.

That works yes.
A bit much to typw though. Don't know if I'd save much time from first doing
a locate and the manually typing the cd [result] string :)

Or type "cd <double-click> <middle-click>"

PS - please don't top-post.

Two is not equal to three, even for large values of two.

Forgot you're still toppost sensitive in this group.
Anyway I don't have a mouse on that system, so I'll have to use Alan
suggestion.

And always will be, once oyu've seen the one true way you don't change :)

You could use a script. e.g.

#!/bin/sh
# cdlocate.sh
cd $(dirname $(locate $1 | head -n 1))

The head -n 1 will avoid it falling over when locate returns more than
one hit, although it will still break if there are no hits. Maybe,
although I haven't tested it, something like

FILE=$(locate "$*" | head -n 1))
[[ "${FILE}" ]] && cd $(dirname "${FILE}")

You could use a little shell function like this one. Add it to your 
~/.bashrc or somewhere like that. 

locatecd()
{
        oldIFS=$IFS
        IFS=$'\n'
        results=( $( locate "$1" ) )
        ret=$?
        IFS=$oldIFS
        if (( ret ))
        then
                echo "Sorry, '$1' was not found."
                return $ret
        fi
        if (( ${#results[@]} > 1 ))
        then
                echo "More than one file found, using the first one."
        fi

        cd "$( dirname "${results[@]}" )"
}

Make it a shell function if you need it often.

A script won't help as it will only change the path in the context of the 
script. A shell function is required.

Depends on how you call the script. If you do:

        script

then you're right.

You could however source the script; ie. call:

        . script

It would work if you sourced it, but a shell function would be better.
