Make WGET available without path

Question

I have ready bash script, which extensively uses wget command. Unfortunately wget is not available at standard path, but available at:

/usr/custom/bin/wget

I was able to make it usable w/o path in bash console, by introducing an alias:

alias wget="/usr/custom/bin/wget"

Still it's not seen from bash script:

./deploy.sh: line 312: wget: command not found

How do I make things work without rewriting the script itself?

P.S. ~/.bashrc is available for editing on the box, so I will be happy to persist those changes.

Answer 1

Add it to your PATH in .bash_profile or .bashrc:

export PATH=$PATH:/usr/custom/bin

This if you only want it for an specific user, if you want it for all users, you could add wget path to /etc/environment.

Answer 2

That is because shell do not support your env aliases by default.

There are two ways to solve this issue:

1. use #!/bin/bash -i (in case of bash)

2. add your /usr/custom/bin/ to PATH

Answer 3

You can call your script like this:

PATH=$PATH:/usr/custom/bin/ ./deploy.sh

With this, your PATH is only changed during running process of your script.

Answer 4

You should just extend your PATH in the script. That way other commands in that directory don't clobber your normal use of bash, and you don't have to retype it with every invocation

#!/bin/bash 

PATH=$PATH:/usr/custom/bin/

<rest of your script>
