Should I write an executable -how to?

Hi,
As you can see I have no idea about programming.

I have an app in my /home/download   called look.

Only way i can call this app is to open a terminal in /home/download then type /usr/loacl/bin/look.

I'd like to just type look anywhere/any drectory and  get this prog launched- just like firefox.
(I  can type firefox any terminal it opens up)

I''d rather not mess with the prog look.

I thought if I can have a bin file in /root/bin which will do:

cd /home/download
/usr/local/bin/look

Is this a possibility or is there a better way.

Please don't laugh.

Regards
Ben

Re: Should I write an executable -how to?

well, it looks like you need a shell script, considering the need to "cd" before running the app.

Save the following:

#!/bin/bash
cd /home/download
exec /usr/local/bin/look

to a file called "mylook"

As root, mv that file to /usr/bin and run "chmod 755 /usr/bin/mylook"

From then on, you can just type "mylook".  Be very careful if you name this script "look", because that aready exists:

/usr/bin/look is owned by util-linux 2.12-9

Even better would be:

#!/bin/bash
CURRENT_DIR=`pwd`
cd /home/download
exec /usr/local/bin/look && cd $CURRENT_DIR

The last cd will never get called because "exec" completely overwrites the running process - you'd want to remove the exec if you used shadowhand's version

Re: Should I write an executable -how to?

instead of using

CURRENT_DIR=`pwd`

for the old path you can just use a dash to cd.

cd /home/download
/usr/local/bin/look && cd -
