Why do you need this? envsubst is an auxiliary program for eval_gettext. For example eval_gettext 'The word is $foo' produces a POT file that contains #, sh-format msgid "The word is $foo" msgstr "" If the translator has provided the translation #, sh-format msgid "The word is $foo" msgstr "The word is $xxxx" "msfgmt -c" will produce an error: a format specification for argument 'foo' doesn't exist in 'msgstr' So, the string "The word is $xxxx" will not even end up in a .mo file.
