contest@pride386.PP.COM (contest one liners) (06/07/91)
first I wold like to thank all of you who entered this contest!
here are the entrys that passed the tests...and worked
there noa as portable as I would have liked but then some vendors don't
put everything in there packages;-)
so here they are enjoy, use them but always, don't claim you wrote them
(unless you did ).

Well, the only 1-liner I could find that I use is one I call "uulk":

Oops -- I was wrong: I just found another one ("logins"):
cut -d: -f1 /etc/passwd | sort | pr -8 -t
From: jim@anacom1 (Jim Bacon)
$ for i in `uustat -a | grep mapN | cut -f 1 -d' '`
> {
> uustat -k${i}
> }
This is one line since the shell does not act upon it untill the final
closing brace. I have shown the prompts as they appear on my screen.

With enough gross csh hacking, MBParkerRmailDates and grepRmail can be
combined into a one-line csh alias with something like:
alias MBParkerRmailDates " \
awk ' BEGIN {n= 0; found= 0} \
{line[n]= "'$0'"; ++n} \
/From: mbparker/ {found= 1} \
/"'\037'"/ {if (found) for (l= 0; l<n;++l) {print line[l]}\
n= 0; found= 0} ' *.rmail \
| grep -i Date: | awk '{print "'$5, $4, $3, $6, $7'"}' \
| sort +0 -1 -n +1 -2 +2 -3 -n +3"
However this alias does not work on all csh implementations and is unmodular
and so is hard to read and difficult to debug.

Ok, here's the best ones out of my .cshrc:
alias dszs 'find . -name "\!{*}*" -ls|sort +6n -7|tail -100|sed -e "s/^[ ]*[1-9][0-9]*[ ]*[0-9]* //" -e "s/^d[-r]........[ ]*/d /" -e "s/^-[-r].\(.\)......[ ]*/\1 /" -e "s/^p[-r]........[ ]*/p /" -e "s/^l[-r]........[ ]*/l /" > /var/tmp/junk.$user.dszs.lis ; ls -l /var/tmp/junk.$user.dszs.lis ; tail -40 /var/tmp/junk.$user.dszs.lis'
which at the prompt would be:
find . -name "*" -ls|sort +6n -7|tail -100|sed -e "s/^[ ]*[1-9][0-9]*[ ]*[0-9]* //" -e "s/^d[-r]........[ ]*/d /" -e "s/^-[-r].\(.\)......[ ]*/\1 /" -e "s/^p[-r]........[ ]*/p /" -e "s/^l[-r]........[ ]*/l /" > /var/tmp/junk.$user.dszs.lis ; ls -l /var/tmp/junk.$user.dszs.lis ; tail -40 /var/tmp/junk.$user.dszs.lis
The above lists all files (not beginning with ".") in &/or under the
current directory, sorts them by sizes, takes the 100 largest, strips down
the "ls" listing to just the more essential information, records the results
in a file unique to the current user-name, and spits out the dope on the
40 biggest disk hogs to the screen.
alias purge 'rm -i \!{*}*.bak \!{*}*.old \!{*}*junk* \!{*}*.~* \!{*}*% \!{*}.*% \!{*}.*.old'
which at the prompt would be:
rm -i *.bak *.old *junk* *.~* *% .*% .*.old
This gets rid of some useless junk in the current directory.
In the alias form of the one-liners, the construct " \!{*}" has the purpose
of allowing another directory than the current one, or to specify some
leading pathname component.

SCO Xenix:
cd /usr/spool/lp/request;cd 'cat ../default';ls d0* | sed 's/d0/'`cat
../../default`'/' | xargs cancel
Cancels all pendings requests on the default printer. We really us
it when a client calls and the stupid printer was off-line..
Meanwhile the users spooled the same job 25 times! so we do:
cd /usr/spool/lp/request/PRINTERNAME
ls d0* | sed 's/d0/PRINTERNAME/' | xargs cancel
most of the time PRINTERNAME is 'printer' under SCO Xenix.

uustat -m | sort -r -d +.25
Sorts your UUCP connections by most recent contact. Great if you
want to know what hosts your host has talked to recently.

expr "`echo \`echo '_availmem=X' | adb -p "" /xenix\`"/D" | adb -p '' /dev/kmem`" : '[^ ]*\(.*\)'

expr `expr "\`echo \\\`echo '_availmem=X' | adb -p "" /xenix\\\`"/D" | adb -p '' /dev/kmem\`" : '[^ ]*\(.*\)'` \* 4096
Prints the number of free bytes of memory availble under SCO Xenix.

A contest? OK, So here's my entry, a c shell alias:
I have this line aliased to ccg in my .cshrc.
cc -g -o \!^ \!^.c \!:2* >& ,e;grep -v ^$ ,e >,e2;rm ,e; if !(-z ,e2) $EDITOR ,e2 \!^.c
It's used like this:
cshprompt> ccg foo <args>
Where foo.c is a stand-alone C program you wish to compile.
Here's what it does:
-tries to compile the foo.c, with optional command line flags for
the linker, putting object file in foo.
-std error goes into a file called ,e
-,e is relieved of any empty lines, and results end up in ,e2
-,e is removed
-if there is still output in ,e2 it means your compiler/linker has written
something to stderr, usually errors, although some compilers write silly
copyright notices to standard error. (if your compiler has that dumb behavior
it will have to be turned off for this script/line to work perfectly).
The script checks for any such error output, and if it exists, calls the
program you have defined in your environment as your $EDITOR, and puts you in
that program editing the error file, with the original .c file as your
secondary file to edit. If you use vi, you can then flip back and forth
between the error file and source code with either \036 [Ctrl-^] or :e #
You can similarly leave out the -g and call your alias CC, or mycc.
[ note.- once in vi type :n then you can flip using [Ctrl ^] or :e # ]

ls|sed -e h -e 'y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/' -e 's/.*/mv \& /' -e G|sh -x
This renames files off a DOS floppy to lowercase. And yes, I *have* typed
this on the shell command line! This can also be used to rename files with
common changes by replacing the y/// with something else, e.g. "s/foo/bar/" to
rename all *foo* to *bar*. (If you do this, use e.g. "ls *foo*" or you may
get a lot of error messages on filenames that *don't* contain "foo".)
