I have a variable that contains this kind of string :
var='$FOO/bar/baz*'
and I want to replace the variable $FOO by its content. However, when i do
var=$(eval "echo $var")
The variable is replaced, but the star is also replaced so that var
now contains every possible match in my filesystem (as if i pressed tab in a shell). for example, if $FOO contains /home, var
will contain "/home/bar/baz1.sh /home/bar/baz2.sh /home/bar/baz.conf"
How do i replace the variable without expanding wildcards ?
Turn off globbing in bash, then reenable it.
set -f
var="$FOO/bar/baz*"
set +f
Just drop the quotes:
var=$FOO/bar/baz/*
Globs are not expanded on the RHS of a variable assignment.
