Create user add lines from partial passwd file

awk -F: '{print "useradd -u "$3,"-c \""$5"\"","-s "$7,$1}' passwd
Handy if you are installing a new server or recovering an old one and you have a passwd file with the accounts you want to add to the server. If you edit the file so that only the accounts that you want to add are left this line will spit out the correct useradd lines. The uid, gecos and shell will be preserved.
Sample Output
jsnuffy:x:600:600:Joe Snuffy:/home/jsnuffy:/bin/bash
hhandle:x:601:601:Harru Hoehandle:/home/hhandle:/bin/bash
ssimple:x:602:602:Sally Simple:/home/ssimple:/bin/bash

useradd -u 600 -c "Joe Snuffy" -s /bin/bash jsnuffy
useradd -u 601 -c "Harru Hoehandle" -s /bin/bash hhandle
useradd -u 602 -c "Sally Simple" -s /bin/bash ssimple

  • The command copies a file from remote SSH host on port 8322 with bandwidth limit 100KB/sec; --progress shows a progress bar --partial turns partial download on; thus, you can resume the process if something goes wrong --bwlimit limits bandwidth by specified KB/sec --ipv4 selects IPv4 as preferred I find it useful to create the following alias: alias myscp='rsync --progress --partial --rsh="ssh -p 8322" --bwlimit=100 --ipv4' in ~/.bash_aliases, ~/.bash_profile, ~/.bash_login or ~/.bashrc where appropriate. Show Sample Output

    rsync --progress --partial --rsh="ssh -p 8322" --bwlimit=100 --ipv4 .

  • Alternately for those without getent or only want to work on local users it's even easier: cut -d: -f1 /etc/passwd|xargs -n1 passwd -e Note that not all implementations of passwd support -e. On RH it would be passwd -x0 (?) and on Solaris it would be passwd -f.

    getent passwd|cut -d: -f1|xargs -n1 passwd -e

  • It can resume a failed secure copy ( usefull when you transfer big files like db dumps through vpn ) using rsync. It requires rsync installed in both hosts. rsync --partial --progress --rsh=ssh $file_source $user@$host:$destination_file local -> remote or rsync --partial --progress --rsh=ssh $user@$host:$remote_file $destination_file remote -> local

    rsync --partial --progress --rsh=ssh $file_source $user@$host:$destination_file
