# Piece-by-Piece Explanation: | |
# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment | |
# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too | |
# the $PROMPT_COMMAND environment variable is executed every time a command is run | |
# see: ss64.com/bash/syntax-prompt.html | |
# we want to update the iTerm tab title to reflect the current directory (not full path, which is too long) | |
# echo -ne "\033;foo\007" sets the current tab title to "foo" | |
# see: stackoverflow.com/questions/8823103/how-does-this-script-for-naming-iterm-tabs-work | |
# the two flags, -n = no trailing newline & -e = interpret backslashed characters, e.g. \033 is ESC, \007 is BEL | |
# see: ss64.com/bash/echo.html for echo documentation | |
# we set the title to ${PWD##*/} which is just the current dir, not full path | |
# see: stackoverflow.com/questions/1371261/get-current-directory-name-without-full-path-in-bash-script | |
# then we append the rest of $PROMPT_COMMAND so as not to remove what was already there | |
# voilà! |
