Problem

[fabien]

Hi!

I have the following problem:

I have a file say toto that contains a list of directories like

/data/tt
/data/mm
...

from those directories I want
1) to search for all files in *.w3s
2) sort them by date and owner and get a list of unique owners
3) run finger -m on each owner to get some info about he owner
4) output the result to a file

Can this be done in Awk? or Cshell?

Thanks!

This should get you started
You may have to adapt this to your shell :
#!/bin/ksh
>filelist
>finger.txt
for dirs in `cat toto`
do
ls $dirs/*.w3s|cut -c16-23 >> filelist
done
sort -u -ofilelist filelist
for users in `cat filelist`
do
finger -m $users >> finger.txt
done

Probably easier in a shell rather than awk,

#!/bin/bash

# print owner of each w3s file in the list of dirs
for i in `cat toto` ; do
  ls -l $i/*.w3s | awk '{print $3}'
done > users

# produce a unique list
sort -u -o users users

# do finger on each user
for i in `cat users` ; do
  finger -m $i
done > results

thanks a lot guys! what about if I only want the users from a specific date say since begining of the year or on a monthly basis?

Thanks!

Use the find command

Eg, this one finds all files modified in the last 30 days

for i in `cat toto` ; do
  find $i -name "*.w3s" -mtime -30 -ls | awk '{print $5}'
done > users

The find command is pretty powerful, so there are lots of options for finding files by various criteria

Thanks again. Last thing: when there are no .w3s files in the directories where the search is done I get lines like /directorypath/*.w3s: no such file or directory, how can I get rid of them?

> /directorypath/*.w3s: no such file or directory
Mmm, you only get that when you do the 'ls' command, not the 'find' command.

But this is what you would use
ls -l $i/*.w3s 2>/dev/null | awk '{print $3}'
