Counting total users

wow, back again Smilie

I am trying to write a program that has many functions, however one of the functions will count the total number of users in the database.


I want to just use wc -l passwd (i've made a copy of passwd to play with, no worries lol)

but I am worried that if any of the accounts contained enough info to be longer than one line of text, it would mess up. Am I correct in my assumption, or does unix read an extended line still as one line?

should I use the 'cut' command to just read the first field? If so, how?

I dunno how different other versions of unix/linux are, but my passwd file is done like this:
root:x:0:0:root:root:/bin/bash


also, how would like to save the number of users as a variable, but not include the name of the file ('wc -l passwd' gives me a reply of # passwd, and i dont want the word passwd to show up)

thanks in advance!

mkpwdict(1M)						  System Administration Commands					      mkpwdict(1M)

NAME
mkpwdict - maintain password-strength checking database SYNOPSIS
/usr/sbin/mkpwdict [-s dict1,... ,dictN] [-d destination-path] DESCRIPTION
The mkpwdict command adds words to the dictionary-lookup database used by pam_authtok_check(5) and passwd(1). Files containing words to be added to the database can be specified on the command-line using the -s flag. These source files should have a single word per line, much like /usr/share/lib/dict/words. If -s is omitted, mkpwdict will use the value of DICTIONLIST specified in /etc/default/passwd (see passwd(1)). The database is created in the directory specified by the -d option. If this option is omitted, mkpwdict uses the value of DICTIONDBDIR specified in /etc/default/passwd (see passwd(1)). The default location is /var/passwd. OPTIONS
The following options are supported: -s Specifies a comma-separated list of files containing words to be added to the dictionary-lookup database. -d Specifies the target location of the dictionary-database. FILES
/etc/default/passwd See passwd(1). /var/passwd default destination directory ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ SEE ALSO
