[Libguestfs] [PATCH] 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". In this case, try to unset it again with the -f option which can handle the parentheses in the supplied identifier. --- dib/dib.ml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/dib/dib.ml b/dib/dib.ml index d730527..e77d75d 100644 --- a/dib/dib.ml +++ b/dib/dib.ml @@ -283,7 +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 ) ;; - *) unset $envvar ;; + *) unset $envvar 2>/dev/null || unset -f $envvar;; esac done fi -- 2.4.3
