#70347 — Will Linux-style commands work on OSX?

I have my iMac G4 running 10.4.11, and my Thinkpads run enterprise Linux 
6.6.  Would I have to download some Mac-specific CL program?  I have a 
Fedora book with tons of Linux commands, will those work?

I take it you mean Red Hat Enterprise Linux 6.6.

Mac OS X is Unix. Linux is based on Unix.
/Applications/Utilities/Terminal is built into Mac OS X and lets you
access the command line.

Depends on the command. Since Linux is based on Unix, a lot of commands
will work the same way or similarly. Mac OS X is different in many areas
though.

The biggest difference is that OS X is a BSD and Linux is.. Well, Linux.

But quite a few of the commands on OS X commands are the GNU versions. 
It's a hodgepodge. You pretty much have to check every command on a 
case-by-case basis to see precisely which options it takes.

Sure, just like in FreeBSD.

Not really. You will get some differences every now and then, but rarely.

For example, I was recently trying to add a from field to messages sent
via root's crontab. The syntax for this on a linux system is

| mail -s "Subject" foo@bar.com -- -f bar@foo.com

That syntax doesn't work in FreeBSD.

Unfortunately, it hits some pretty popular commands. For instance, there 
are frequent questions on Stack Exchange regarding the "sed" command. On 
Linux you can write:

sed -i 's/foo/bar/' files...

to update all the files in place, but on OS X you have to write:

sed -i '' 's/foo/bar/' files...

because the BSD sed expects the backup file suffix to be a separate 
argument.

That looks pretty weird to me. The "--" option is usually used to signal 
the end of all options, everything else after that is non-option 
arguments. I wonder why you would put the "-f" option after it. On any 
flavor of Unix I'd write it as:

mail -s "Subject" -f bar@foo.com foo@bar.com

On linux the flags after the -- are passed to sendmail.

> mail -s "Subject" -f bar@foo.com foo@bar.com

on FreeBSD that returns:

mail: Cannot give -f and people to send to.

many commands that work different on OSX can be "updated" to recent 
versions with well-known linux behaviour through homebrew 
(http://brew.sh/)

Have you tried them in Terminal and if not why not?

If you still have the OS-X install disk, you can optionally install
X-window on the Mac. If you enable IP incoming connections, you can have
Linux Xterms  displayed on your mac, or vice versa.

The Terminal app on the Mac gives you access to command line, but cannot
be displayed on other nodes.

You can also enable telnet or ssh into your Mac from Linux.

The environment is that of freeBSD.

Some stuff is missing, and there is stuff on command line not present in
Linux. (such as many OS-X management utilities).

Depends - I can say with absolute certainty (since I'm also running 
10.4.11) that "Terminal" puts you into a BASH shell (unless you've 
configured it to use another shell, of course) from which you can do 
pretty much anything that any other *nix can do, provided you've got the 
program (if it isn't a built-into-the-shell operation) to do it. 

If you don't have the program, you can probably find a version for the 
Mac. If you can't find one "ready-to-use", you can often find it in 
source code and compile it yourself. 

Basically, as long as you've got a version of the program that does 
"Linux command 'X'" that's built for the Mac, you can do the same thing 
that you could do under any other *nix.

Linux is POSIX compliant and so is BSD/OSX. Most commands will work. 
10.4 uses the BASH shell unless you change it yourself.

List a few of the commands you have in mind. All the basic stuff is 
built in to OS X. I forget which Darwin come with 10.4.x.

So, things like

ls
du
df 

and awk and grep and so on work normally. Or were you thinking of more 
esoteric stuff (mpg123, say)?
