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!

What Others Think

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.

It's much different than env, thats odd if sete and env are displaying the exact same environment. Thats because env is a command, usually in /bin/env or /usr/bin/env so it is executed like any other executable, by calling execve with the current environment, but not the bash environment, whereas set is a shell builtin which shows all the bash internal variables and the current executing environment of bash. For example, do a cat /proc/$$/environ On my machine, env does not show the following vars that sete shows: BASH BASH_ARGC BASH_ARGV BASH_LINENO BASH_SOURCE BASH_VERSINFO BASH_VERSION COLUMNS DIRSTACK EUID GROUPS HOSTTYPE IGNOREEOF INTERACTIVE LINES LOGIN_SHELL MACHTYPE MAILCHECK OPTERR OPTIND OSTYPE PPID PS2 PS3 PS4 SECONDS SHELLOPTS SOURCED UID But if you want to see ALL the hidden variables within bash, check out: http://www.commandlinefu.com/commands/view/6899/print-all-environment-variables-including-hidden-ones

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'
