command execution

vaalu · 08-23-2010, 01:24 AM

hi all,

I have a shell script which is executable in a folder named build. What i currently do is cd into the build directory from my home folder and do a ./make.sh ... Is there any way i can run this executable from my home directory itself??

Something like ./vaalu/ADK/build/make.sh??

the path to the make shell script is

/home/vaalu/ADK/build/make.sh

Any help would be appreciated.
Thanking you in anticipation

regards,

Vishnu Prasad H

Sure. You can type:

Quote:

vaalu/ADK/build/make.sh

<= You don't need the "."

If you need to do this often enough, you can do any of:

a) edit your .bashrc file and include value/ADK/build in your $PATH
<= that way, you can just type "make.sh"

and/or

b) Create an alias for "make.sh" (for example, "mk")

and, of course,

c) You can always create a desktop shortcut (if you use a GUI)

PS:
If you do any of this, you should definitely modify "make.sh" to "cd" into the correct directory before it tries to build anything.

The script may assume you are in the current directory. You could use "pushd ./vaalu/ADK/build" first and the "popd" afterwards. If its something you often, you can use "CTRL-R pushd" to recall it from the bash history, or enter parts of the path, and press TAB for autocompletion.

A script such as
TARGETDIR=/home/vaalu/ADK/build
RETURNDIR="$PWD"
cd "$TARGETDIR"
. ./make.sh
cd "$RETURNDIR"

in your ~/bin/ directory may automate the process for you.

As Paul highlighted, be very careful what commands are in your script as if they are using relative paths from where you launch the script it could
get very messy

What jschiwal and grail wrote. In this case, where the script is called make.sh, suggesting a software build utility, it is not just possible that the utility assumes the correct working directory -- it is very probable because it is such a common build programming technique.
