field separator

[Shivkumar]

Dear Sirs,

I am using $ps -ef|awk '{print $2 $3}'.
I want to insert field separator between two fields to distinguish the output.

Can anyone help me ?

Thanks,
Shiv

hi

try:
ps -ef|awk '{print $2 " " $3}'

hi again,

the separator can be any character that you would be putting between the double quotes:

e.g. "-" or "|"

ps -ef|awk '{print $2 "|" $3}'

or ps -ef|awk '{print $2 "-" $3}'

Hi,

You also use a comma if you just want to seperate in 2 columns

$ps -ef|awk '{print $2,$3}'

Cheers,

Shiv,

you can both use " " and , between line
selections so;
$ps -ef|awk '{print $2,$3}'
or
ps -ef|awk '{print $2 " " $3}'

Good Luck,

Shivkumar,

You can customize the field separator to whatever you want i.e. comma, bar, carriage return etc. as long as you specify it within your awk construct like:

# ps -ef | awk '{OFS="";print $2, $3}'

I'll say go by the Sandman's OFS.

There will be many situations where you have to use OFS.
Situations like where your field data contains spaces, tabs and special characters then only OFS will come to your rescue.

You can further use printf instead of print to have more control over the output.

ps -ef|awk '{printf("%s | %s\n", $2,$3);}'
