finger and usernames

[fabien]

Hi!

I have a file which contains a list if usernames and I would like to get a new file with columns like

"username" "In real life" (output from finger -m "username")

Many thanks!

man awk

Try

for u in $(cat usernamelist)
do
  echo $u is in real life $(awk -F : '/'"$u"'/{print $5}' /etc/passwd)
done >> userlistwithfullnames

Another way:
man join

I can use /etc/password

I need something like that but this gives syntax error

#!/usr/bin/csh 

for u in $(cat usernamelist)
do
  echo $u is in real life finger -m $u | awk '{ if (NR==1) {print $7 $8} }'
done >> userlistwithfullnames

You need to get the output of the finger. There are two options

for u in $(cat usernamelist)
do
  echo $u is in real life $(finger -m $u | awk '{ if (NR==1) {print $7 $8} }')
done >> userlistwithfullnames

or

for u in $(cat usernamelist)
do
  echo "$u is in real life \c"
  finger -m $u | awk '{ if (NR==1) {print $7 $8} }'
done >> userlistwithfullnames

#!/usr/bin/csh
Why using so buggy shell ?

Thanks for pointing that out - I beleive the $(command) syntax I've used only works under ksh.

PHV why are you so angry?

Anyways I did the following script based on Columb's:

#!/usr/bin/ksh 

#create usersnamelist
ls -l /users | awk '{print $3}' | sort -u > /tmp/usernamelist

# process list to get real life name
for u in $(cat /tmp/usernamelist)
do
  echo "$u is in real life \c"
  finger -m $u | awk '{ if (NR==1) {print $7 " " $8} }'
done >> userlistwithfullnames

#cleanup
rm -f /tmp/usernamelist

However for some users finger -m returns In real life: # some name but for other I get In real life:toto.titi@tt.com

is there a way to extract the full name after # and toto titi depending on the case?

I'm not angry, I just pointed out that ksh-like syntax is not advisable for csh and that csh is deprecated since a while ...

You don't need to use the temporary file

for u in $(ls -l /users | awk '{print $3}' sort -u )
do
  echo "$u is in real life \c"
  finger -m $u | awk '{ if (NR==1) {print $7 " " $8} }'
done >> userlistwithfullnames

To deal with the different cases you need to look at the awk syntax, as PHV says 'man awk'. This is quite a maor topic and has it's own forum. As finger is getting this info from /etc/passwd why don't you cut out the middleman and use awk to get it directly?
