Creating ALIAS

eco_bach · 10-06-2018, 09:15 AM

Hi

Can anyone tell me if the following syntax is correct? I'm prepending my PATH variable then launching houdini

Quote:

> alias houdini_run='pathold=$PATH; PATH=/home/jim/yt-conda/bin:/home/jim/yt-conda/sbin; /opt/hfs16.5.595/bin/hindie-bin; PATH=$pathold'

The problem is when I run it, houdini DOES launch but I'm seeing a lot of missing package errors even though they definitely ARE installed in the bin directory defined in the above PATH.

ie

Quote:

> sh: 1: grep: not found

> sh: 1: awk: not found

> sh: 1: ls: not found

Why don't you add those directories to PATH with your user's .bashrc or .bash_profile ?

The errors are raised because you are removing all others directories from PATH. You need to ADD your directories to PATH.

Code:

PATH=$PATH:<add yours>

The grep, awk and ls commands are system-wide commands that should already be in folders in the $PATH

The syntax for the alias command is quite simple.

Code:

alias <command_here>='<command and options for it here>'

For example if I wanted to run the ls command with the -la option every time I run ls, it would be the following;

Code:

alias ls='ls -la'

You seem to have semicolons mixed in with the colons. I'm not sure what that alias is supposed to do.

afaik, aliases don't do variables.
it would explain the problems your houdini causes, if it executes PATH=''.
i think you want a function in ~/.bashrc or a script in ~/bin.

I'm inclined to follow the original thread for this "houdini who-dunnit"

Just sayin'
