Shell Programming and Scripting

Hello all,

This beats me. I have a script that executes some commands and redirects their output to some text files that I will parse. The commands are along the lines of:

dsmadmc -id=admin -pa=admin -outfile=/home/tools/qlog.txt q log f=d

If I just run the script it works. If I execute it from the command line, the output looks like this:

[root@portdat:/home/tools] cat qlog.txt

If I | more it, the output looks like this:

This is not even the command. It looks like two things are happening: the format is being screwed up somehow, and the f=d option is not being executed. Any ideas?

This is on AIX 5.2 using the ksh.

Thanks for any input,

Michael

First off, your second example (where you state you are using | more ) - shows the command cat qlog.txt - so I must assume you were using the | more on the end of dsmadmc -id=admin -pa=admin -outfile=/home/tools/qlog.txt q log f=d I don't understand why since you are setting an output file.

(No, I'm not an AIX sa and don't have access to AIX - just going on instinct )

The ls program will do stuff like this on most systems. Maybe AIX is an exception. But for me, "ls" and "ls | more" give different results. I am forced to do a "ls -C | more" to see the equivalent of "ls'. What is happening is that the ls program is looking at stdout and checking to see if it's a tty or not. If it is a tty, it defaults to -C. Any program can do that, but to do so is controversial to say the least. All I can suggest is to check the man page for your command and see if there is an option to give you the result you want. Possibly the program is innocent and it's the script that is doing this. To see the syntax, try these commands from a ksh prompt:
{ [ -t 1 ] && echo yes; }
{ [ -t 1 ] && echo yes; } | cat

The first should print "yes" but the second should print nothing. Check your script for stuff like that.
