Script to convert /etc/passwd to useradd command line
This is a very simple script to convert a /etc/passwd file to the associated useradd command line that creates the account. Useful for when your brain has turned off and you’re mid migration to a new system. Works with Linux and Solaris.
#!/usr/bin/perl -w use strict; while(<>) { chomp; my @a = split /:/; print 'useradd '; print '-d ' . $a[5] . ' ' if(defined $a[5]); print '-m -u ' . $a[2] . ' -g ' . $a[3] . ' ' ; print '-c "' . $a[4] . '"' if(length $a[4] > 0); if (!defined $a[6]) { $a[6] = "/usr/bin/false"; } print ' -s ' . $a[6] . ' ' . $a[0] . "\n"; }
