| [[Anchor(faq67)]] == How can I trim leading/trailing white space from one of my variables? == There are a few ways to do this {{{ #POSIX read -r var << EOF $var EOF }}} One can also achieve in bash (and ksh93) using a herestring {{{ # Bash # Remove leading whitespace: read -r x <<< "$x" }}} There's also a solution using [:glob:extglob]: {{{ # Bash shopt -s extglob x=${x##+([[:space:]])} x=${x%%+([[:space:]])} shopt -u extglob }}} This also works in KornShell, without needing the explicit `extglob` setting: {{{ # ksh x=${x##+([[:space:]])} x=${x%%+([[:space:]])} }}} There are many, many other ways to do this, using sed for instance: {{{ # POSIX x=$(echo "$x" | sed -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//') }}} These are not necessarily the best, but they're known to work. |
