Hi All,

need your help here.

i want create a script that will read

1. user.txt ( probably will have 20 - 50 user list)
2. alert.txt (only have 1 line)

lynx -dump "http://localhost/cgi-bin/alert?user=$user&text=$alert"

So far i only managed to use looping

for user in `cat user.txt `; do lynx -dump "http://localhost/cgi-bin/alert?user=$user&text=i have to set this manually";done

Is there any workaround ?

Thanks.

Code:

alert = cat alert.txt
users = `cat users.txt`

for user in $users ; do
  lynx -dump "http://localhost/cgi-bin/alert?user=$user&text=$alert"
done

This is what you have essentially correct? What is wrong with it or are you just looking for process improvement?

No spaces around the 'equals' sign in assignments in bash. But you don't need all that backtick stuff anyway

Code:

read alert < alert.txt
while read user; do 
    lynx -dump "http://localhost/cgi-bin/alert?user=$user&text=$alert"
done < users.txt

--- rod.

problem solved :

#!/bin/sh
calert=`cat alert.txt `
cuser=`cat user.txt `
for ccuser in $cuser; lynx -dump "http://localhost/cgi-bin/alert?user=$ccuser&text=$calert" ; done

Note that it's best to use $(command) instead of backticks, since it can't be confused with single quotes and nests easily.
