Re: [Libguestfs] [PATCH v4] dib: handle unsetting functions in environment

If a function name, with its trailing parentheses, is in the environment , trying to unset it will error out with a message of "not a valid identifier". Handle this as a special case, and unset it with the -f option which can handle the parentheses in the supplied identifier. --- dib/dib.ml | 1 + 1 file changed, 1 insertion(+) diff --git a/dib/dib.ml b/dib/dib.ml index d730527..16149ae 100644 --- a/dib/dib.ml +++ b/dib/dib.ml @@ -283,6 +283,7 @@ if [ -z \"$preserve_env\" ]; then for envvar in `env | grep '^\\w' | cut -d= -f1`; do case \"$envvar\" in PATH | USER | USERNAME | HOSTNAME | TERM | LANG | HOME | SHELL | LOGNAME ) ;; + BASH_FUNC_* ) unset -f $envvar ;; *) unset $envvar ;; esac done
