Variables exportadas no funcionan

[jgrm]

Hola, estoy aprendiendo a hacer scripts en linux y me ha surgido un problemilla que dado mi escaso conocimiento no consigo descifrar.

echo " export EDITOR='leafpad'" >> $HOME/.bashrc
source .bashrc

script:
#!/bin/bash
$EDITOR /ruta/fichero.txt

Si lo ejecuto desde otro script o lanzador de Escritorio no funcuina, pero si lo ejecuto
desde una terminal: ./script, funciona bien. ¿Por que no lo puedo ejecutar desde otro
script o lanzador?. Gracias de antemano.

INVOCATION
A login shell is one whose first character of argument zero is a -, or one started with the --login
option.

An interactive shell is one started without non-option arguments and without the -c option whose standard
input and error are both connected to terminals (as determined by isatty(3)), or one started with the -i
option. PS1 is set and $- includes i if bash is interactive, allowing a shell script or a startup file to
test this state.

The following paragraphs describe how bash executes its startup files. If any of the files exist but can‐
not be read, bash reports an error. Tildes are expanded in file names as described below under Tilde
Expansion in the EXPANSION section.

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option,
it first reads and executes commands from the file /etc/profile, if that file exists. After reading that
file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes
commands from the first one that exists and is readable. The --noprofile option may be used when the
shell is started to inhibit this behavior.

When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, bash reads and executes commands from
~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file
option will force bash to read and execute commands from file instead of ~/.bashrc.

When bash is started non-interactively, to run a shell script, for example, it looks for the variable
BASH_ENV in the environment, expands its value if it appears there, and uses the expanded value as the
name of a file to read and execute. Bash behaves as if the following command were executed:
if [ -n "$BASH_ENV" ]; then . "$BASH_ENV"; fi
but the value of the PATH variable is not used to search for the file name.

Deberías mostrar esos otros scripts desde los cuales estás ejecutando tu ejemplo, pero el problema parece surgir de lo que está explicado allí: bash lee .bashrc o .bash_profile dependiendo de cómo sea invocado.


Saludos.
