PREEMPT_DYNAMIC Thu Sep 12 18:26:09 UTC 2024 x86_64 GNU/Linux
Machine Type: x86_64-redhat-linux-gnu
Bash Version: 5.2
Patch Level: 26
Release Status: release
Description:
In the following script, the first alias fails with "comand not found"
but the second works.
#!/bin/bash
shopt -s expand_aliases
if :; then
alias foo='echo'
foo x y z
shopt expand_aliases
alias -p
fi
alias foo='echo'
foo a b c
Running it produces:
$ ./alias-test.sh
./alias-test.sh: line 7: foo: command not found
expand_aliases on
alias foo='echo'
a b c
This is at least, undocumented behaviour.
Repeat-By:
Run the script in "Description".
