Hello,
in refer to
http://lists.gnu.org/archive/html/bug-bash/2014-09/msg00278.html variables
with suffix "%%" can't be set/exported.
This makes problems restoring environments which where saved by external
programs like printenv (see example below)
I saw this issue on Ubuntu 12.04 with
bash version GNU bash, version 4.2.25(1)-release (x86_64-pc-linux-gnu)
examples:
$ foo() { echo "bar"; }
$ export -f foo
$ echo "export BASH_FUNC_foo%%='$(printenv BASH_FUNC_foo%%)'" | tee ./env
export BASH_FUNC_foo%%='() { echo "bar"
}'
$ source ./env
bash: export: `BASH_FUNC_foo%%=() { echo "bar"
}': not a valid identifier
$ export BASH_FUNC_foo%%='() { echo "bar"; }'
bash: export: `BASH_FUNC_foo%%=() { echo "bar"; }': not a valid
identifier
$ export BASH_FUNC_foo='() { echo "bar"; }'
bucher_l@zim:/vobs/1GP1AdminVob/Tools/ldapadmin$ echo $BASH_FUNC_foo
() { echo "bar"; }
