Parse password file and populate variables

#!/bin/bash

#ypcat passwd > /tmp/passwd
cp /etc/passwd /tmp/passwd

while IFS=: read -r user pass uid gid gecos home shell
do
  echo "ipa-moduser -a -s \"$shell\" -c \"$gecos\" -d \"$home\" $user"
done < /tmp/passwd

exit 0


Another approach...


#!/bin/sh
# 1 is the nis domain, 2 is the nis master server
ypcat -d $1 -h $2 group > /dev/shm/nis-map.group 2>&1
IFS=$'\n'
for line in $(cat /dev/shm/nis-map.group); do
  IFS=' '
  groupname=$(echo $line|cut -f1 -d:)
  # Not collecting encrypted password because we need cleartext password to create kerberos key
  gid=$(echo $line|cut -f3 -d:)
  members=$(echo $line|cut -f4 -d:)
  # Now create this entry
  ipa group-add $groupname --desc=NIS_GROUP_$groupname --gid=$gid
  if [ -n "$members" ]; then
    ipa group-add-member $groupname --users=$members
  fi
  ipa group-show $groupname
done
