[Fwd: [olug] Unix Tip: AWK THE STATS]

[Jay Hannah]

Ouch. 15 lines of awk? How about:

   cut -d: -f 7 /etc/passwd | sort | uniq -c

instead? You know something is simple when even I don't recommend a
little Perl script. -grin-

AWK THE STATS


AWK script for getting 
statistics.

The script gives the 
statistics of the default 
shell set for the users.

i.e. Number of users using 
csh,ksh or sh

$cat stat_demo.awk
#start here
BEGIN{
FS=":"
#seperator is set to :
}
{
#$7, is 7 field in passwd file
  stat_array[$7]=stat_array[$7]+1;
}
END{
print "Login-Shell Count" ;
for (i in stat_array) print i, stat_array[i]
#Displays statistics
}       
#end here


To use this , Just say

awk -f stat_demo.awk /etc/passwd

or

cat /etc/passwd | awk stat_demo.awk
