Output redirection

Hello i am trying to write a script that will redirect the output to a certain file. Here is the code so far:

Code:
#!/bin/bash
ps -e | sort | more > psfile

When I execute the script nothing happens since i assume the output was redirected to the file called psfile. When I try to look at the psfile, I get the following:

Code:
[root@localhost manny]# psfile
./psfile: line 1: 10: command not found
./psfile: line 2: 1: command not found
./psfile: line 3: 11: command not found
./psfile: line 4: 1249: command not found
./psfile: line 5: 1250: command not found
./psfile: line 6: 1310: command not found
./psfile: line 7: 140: command not found
./psfile: line 8: 141: command not found

Am I missing something here? Do I have to create the file "psfile" before running the script?

Hi.

Nothing "happens" because the output went to psfile, not to the screen / terminal.

Code:
#!/bin/bash
ps -e | sort | more > psfile

(not sure why more is required)

You're not trying to look at the file, you're trying to run it.

Code:
[root@localhost manny]# psfile

(although how you can do that straight after creating it, if you didn't have another command (chmod) to allow you, suggests that you might be using Cygwin, or some such)

To look at the file:
Code:
[root@localhost manny]# cat psfile
# or
[root@localhost manny]# less psfile
# or
[root@localhost manny]# vi psfile
# etc.
