Dear Admin,
I'm writing a script whose goal is to find a free uid in NIS secure passwd
file.
The passwd file syntax is the following one:
username:##username:uid:gid:...
I was thinking about using egrep:
------------------------------------------------------------------------
# Starting with uid 5010
uid=5010
# Looking for a free user uid in NIS passwd file
rep=`egrep ':'$uid':' ${NIS_PATH}/passwd`
while [ "$rep" != "" ]
do
let uid+=1
rep=`egrep ':'$uid':' ${NIS_PATH}/passwd`
done
echo "User user id "$uid" can be used..."
exit 0
------------------------------------------------------------------------
This works fine except that regular expression ':'$uid':' can also match
gid...
What I would like to do is egrep ':##*'$uid':' ${NIS_PATH}/passwd but this
doesn't work.
Do you know a way to do that ?
Thanks in advance for your help.
Regards,
Sabrina Lautier
