Both A and B are untouched so B IS NOT the former A. Right?
Yes. This is what i'd expect.
I'd also expect some diagnostic message to be issued (i don't have OS X but i suppose it would be something along the lines of "Error: cannot ....") and the return-code to be non-zero. This is a common trait of UNIX-commands: whenenver they cannot do what is asked they will return a non-zero error code. Try the following:
/etc/hosts is a file supposed to exist, so the return code should be zero, the second file does not exist, so the error code will be presumably 2 (if OS X-ls works the same way as my ls on AIX, the value might differ but it should be non-zero in any case).
i'm using SunOS 5.7 and I know theres a ls option for seeing what kind of files are in a directory. I was wondering if there was a ls option that could see if the files are txt or files that can be opened in vi (1 Reply)
How can I use the 'ps' command to view current sessions but only for a given process/user, with the -u parm?
In older versions of Unix, this used to work, but not in Sun Solaris.

GROG(1) General Commands Manual GROG(1)NAME
grog - guess options for groff command
SYNOPSIS
grog [ -option ... ] [ files ... ]
DESCRIPTION
grog reads files and guesses which of the groff(1) options -e, -man, -me, -mm, -mom, -ms, -mdoc, -mdoc-old, -p, -R, -g, -G, -s, and -t are
required for printing files, and prints the groff command including those options on the standard output. A filename of - is taken to
refer to the standard input. If no files are specified the standard input will be read. Any specified options will be included in the
printed command. No space is allowed between options and their arguments. The only options recognized are -C (which is also passed on) to
enable compatibility mode, and -v to print the version number.
For example,
`grog -Tdvi paper.ms`
will guess the appropriate command to print paper.ms and then run it after adding the -Tdvi option.
