Display environment vars only, using set

alias sete='set|sed -n "/^`declare -F|sed -n "s/^declare -f \(.*\)/\1 ()/p;q"`/q;p"'
Normally the bash builtin command 'set' displays all vars and functions. This just shows the vars. Useful if you want to see different output then env or declare or export. Alias 'sete' shows sets variables alias sete='set|sed -n "/^`declare -F|sed -n "s/^declare -f \(.*\)/\1 ()/p;q"`/q;p"' Alias setf shows the functions. alias setf='set|sed -n "/^`declare -F|sed -n "s/^declare -f \(.*\)/\1 ()/p;q"`/,\$p"' Also see: http://www.commandlinefu.com/commands/view/6899/print-all-environment-variables-including-hidden-ones At the very least, some cool sed commands!

Just thinking how is this different from: env

OK, did not notice your work on 'setf' before. There seems no built-in alternative to 'setf' though.

cat /proc/$$/environ vs: cat /proc/$PPID/environ or with strace you can compare: strace -v -f -e trace=execve /bin/env and stracing bash is harder, but: strace -v -f -e trace=execve /bin/bash -i -l -c 'set'
