NAME=${MYVAR%:*} # retain the part before the colon
NAME=${NAME##*/} # retain the part after the last slash
${MYVAR#pattern} # delete shortest match of pattern from the beginning
${MYVAR##pattern} # delete longest match of pattern from the beginning
${MYVAR%pattern} # delete shortest match of pattern from the end
${MYVAR%%pattern} # delete longest match of pattern from the end
So #
means match from the beginning (think of a comment line) and %
means from the end. One instance means shortest and two instances means longest.
${MYVAR:3} # Remove the first three chars (leaving 4..end)
${MYVAR::3} # Return the first three characters
${MYVAR:3:5} # The next five characters after removing the first 3 (chars 4-9)
${MYVAR/search/replace}
