Vi mode is also available in zsh and dash shells. Note: Zsh is using it's own command line editor (ZLE), and Dash only if is linked against editline¹ (though there is no support for multibyte characters). And vi mode is specified in POSIX, http://www.opengroup.org/onlinepubs/009695399/utilities/sh.html#tag_04_128_13_03 As a side note and a bit of topic (but since Bash was mentioned and I can't really understand Bash's popularity) and anyway I can't understand why the Linux distributions ships with Bash as the default shell. Zsh is some <exaggeration> thousands times </exaggeration> better as an interactive shell!, and Dash it serves better for login and system scripts because is much faster and stable than Bash (Ubuntu is using Dash as /bin/sh and Debian is going to follow). The only excuse is, for writing extensive shell scripts (using specific Bash extensions). But in my opinion if you are going to write a complicated shell script, again is better and faster, to use a portable scripting language like Ruby or Python, than to rely on unportable Bashisms. Dash also can be used to write shareable portable scripts between POSIX systems. Here is an old benchmark (a loop) to compare the differences: i=0 start=$(date +%s) while [ "$i" -lt "10000000" ]; do i=$(($i+1)) done echo "total time" $(($(date +%s) - $start)) "seconds" bash : 332 seconds in UTF-8 bash : 220 seconds in C locale dash : 64 seconds zsh : 106 seconds # A similar (in logic) loop in Vim, C and some scripting languages just for a comparison: vim : 45 seconds C : 0 seconds lua : 02 seconds python: 04 seconds perl : 04 seconds ruby : 05 seconds 1. http://www.thrysoee.dk/editline/ > Anton.
