git-sh-i18n--envsubst

eval_gettext () {
        printf "%s" "$1" | (
                export PATH $(git sh-i18n--envsubst --variables "$1");
                git sh-i18n--envsubst "$1"

}

This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the plumbing scripts and/or are writing new ones.

git sh-i18n--envsubst is Git’s stripped-down copy of the GNU envsubst(1) program that comes with the GNU gettext package. It’s used internally by git-sh-i18n(1) to interpolate the variables passed to the eval_gettext function.

No promises are made about the interface, or that this program won’t disappear without warning in the next version of Git. Don’t use it.
