If you wanted to be wicked-gross, you could look for perl and do:
perl -e 'print "uid=$> euid=$< groups=$( egroups=$)\n";'
Or write a small C program to do the same and hunt for the compiler. This is
probably a bit too much, but you could do it.
Other things that muck with uid are:
whoami
/proc/self/status
Or you could use a bit-o-shell-script like:
#! /bin/sh -f
#
#
function error() {
echo "$0: failed: $1" 1>&2
exit 1
}
function getUID() {
guess=`grep $1 /etc/passwd`
if [ -z "$guess" ]; then
guess=`ypcat passwd | grep $1`
test -z "$guess" && error "Can't find user id"
fi
uid=`echo $guess | cut -f 3 -d :`
gid=`echo $guess | cut -f 4 -d :`
}
function getGroup() {
guess=`grep $1 /etc/group`
if [ -z "$guess" ]; then
guess=`ypcat group | grep $1`
test -z "$guess" && error "Can't find user id"
fi
agroup=`echo $guess | cut -f 1 -d :`
}
function getGID() {
guess=`grep $1 /etc/group`
if [ -z "$guess" ]; then
guess=`ypcat group | grep $1`
test -z "$guess" && error "Can't find user id"
fi
agroup=`echo $guess | cut -f 1 -d :`
agid=`echo $guess | cut -f 3 -d :`
}
user=`whoami`
groups=`groups`
getUID $user
getGroup $gid
echo -n "uid=$uid($user) gid=$gid($agroup) groups="
for g in $groups; do
getGID $g
echo -n "$agid($agroup) "
done
echo ""
which pretty much does the right thing, though needs to be changed to do
exactly the right thing.
