Apparently they never read the 1978 bell labs technical journal article on how you build commands out of lesser commands, rather than jamming all the functionality into every command. On the other hand, I've often found it annoying that the 'ls' command doesn't display 'ps' information, like it does on Linux... not. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Re: Questions about -current (Linuxism's)
While I realize you can't emulate the switches on any command on any os, I found a few "linuxism's" missing. Eg: I find it illogical, that "route" can change, and also display the route to a single host, but route can not display the entire route table. In linux it is simply "route", in windows it is "route print", but in FreeBSD it is "netstat -r" It is simple to add an information "Sorry Dave, I can not do that. Try netstat -r instead" for "route print" (I just did), or adding similar information when no proper keyword is given. Similarly on linux "netstat -ap"; the p gives the pid which has the connection open. On FreeBSD, this option is not available, instead sockstat provides similar (better; it shows the path to the command) information. As the -p is not used for netstat, it could print "use sockstat instead". It could help in heterogenious environments. Or perhaps this would just start a slide down a slippery slope... There is always diffence between commands on different os's. Some are even "dangerous". Eg. if you type "hostname -f" on a sun, you change the hostname to "-f"...

Sorry for the confusion there :-) The -a and -x options are meant
for cp(1). The -a (--archive) option in cp(1) for linux (which I am
fairly certain is the gnu version) is essentially an easy way to safely
do -dpR automatically. So effectively -a (--archive) preserves links,
tries to preserve permissions, and also does a recursive copy. The -x
(--one-file-system) option in cp(1) for linux says that if you have
multiple file systems mounted on top of / and you do a `cp -ax /
/mnt/copy/of/root/.` it should only copy the directory stubs for the
mounts instead of the mounts themselves. I have found both of these
options to be extremely useful at times.

Again, sorry for the misunderstanding and not providing enough
information upfront. In linux date(1) is the gnu version of date, which
means you can do the following `date --date 'Jan 22 2002'` and it would
output the following:
Tue Jan 22 00:00:00 CST 2002
Or I could do a `date --date '2 days ago'` and it would output:
Sun Jan 20 00:46:30 CST 2002
Again, this option might not be the most useful thing in the world
but I know that I have used it many times at home and at work to make
scripts less complicated.

Thank you for the response and let me know if you need any further
information to be able to tell what the options I was refering to for
cp(1) and date(1) actually do.

What does the -a or -x option do for the ls(1) command of Linux?
Perhaps equivalent options do already exist in FreeBSD ls(1).

If I haven't misunderstood you on this, FreeBSD's date(1) can already
do what you want, although I have to admit that it works a bit
differently than Linux's date(1).
I've recently used date(1) -j and -f options to convert arbitrary
dates to the local timezone in a script I wrote to print the
modification date of problem reports. You might want to check the
scripts at:
http://people.FreeBSD.org/~keramida/pr/feedback/
for samples of using date(1) to convert between timezones and date
representations. A small example that will probably help you
understand how this is done (combined with the description of the -j
and -f options in the date(1) manual page) is shown below:
hades!charon:[/home/charon]% date '+%s => %T %Z'
1011645430 => 22:37:10 EET
hades!charon:[/home/charon]% TZ=UTC date -j -f '%s' 1011645328 '+%s => %T %Z'
1011645328 => 20:35:28 GMT

Re: Questions about -current
First off, you sent this to the wrong list. Most of the questions you bring up in here should have been directed at -questions.
