  • Alias doesn't work inside a Bash script

    2 answers




I have some commands I would like to run in the following order:



HEADAS=/home/warano/HEASoft/heasoft-6.24/x86_64-pc-linux-gnu-libc2.27

export HEADAS 

alias heainit=". $HEADAS/headas-init.sh" 

heainit

CALDB=/home/warano/NUSTAR/caldb

export CALDB 

source $CALDB/software/tools/caldbinit.sh


I put all of these in a script called run-nu_tools.sh, but it does not work so I got this output:



./run-nu_tools.sh: line 6: heainit: command not found


However heainit works if one runs everything in the terminal(step by step) so I want to run all at once, do you have any tips?

The problem is that aliases are not expanded if the shell is not interactive:




ALIASES: Aliases are not expanded when the shell is not interactive unless the expand_aliases shell option is set using shopt.



source: man bash




Add the following to your script:



shopt -s expand_aliases
