Aliases in subshell / child process
Aliases are not inherited. That's why they are traditionally set in bashrc
and not profile
. Source your script.sh
from your .bashrc
or the system-wide one instead.
If you want them to be inherited to sub-shells, use functions instead. Those can be exported to the environment (export -f
), and sub-shells will then have those functions defined.
So, for one of your examples:
rmvr() { rm -rv "$@"; }
export -f rmvr
If you have a bunch of them, then set for export first:
set -a # export the following funcs
rmvr() { rm -rv "$@"; }
cpvr() { cp -rv "$@"; }
mvrv() { mv -rv "$@"; }
set +a # stop exporting
It is because /etc/profile.d/ is used only by interactive login shell. However, /etc/bash.bashrc
is used by interactive non-login shell.
As I usually do set some global aliases for system, I have started to create /etc/bashrc.d
where I can drop a file with some global aliases:
HAVE_BASHRC_D=`cat /etc/bash.bashrc | grep -F '/etc/bashrc.d' | wc -l`
if [ ! -d /etc/bashrc.d ]; then
mkdir -p /etc/bashrc.d
fi
if [ "$HAVE_BASHRC_D" == "0" ]; then
echo "Setting up bash aliases"
(cat <<-'EOF'
if [ -d /etc/bashrc.d ]; then
for i in /etc/bashrc.d/*.sh; do
if [ -r $i ]; then
. $i
fi
done
unset i
fi
EOF
) >> /etc/bash.bashrc
fi
