Does anyone know what __read_nocancel does and why it would go into an infinite loop?

What I have gathered in my searches is that it pertains to server code. Yet, I'm not running this application...

Apparently I do not have truss available to me.

/home/mal> man truss
No manual entry for truss
/home/mal> which truss
/usr/bin/which: no truss in ( ... )

Additionally, it looks like ulimit...

Production C code compiled without the dash-g option is running, and seems to be in an infinite loop. Is there a way to tell? Is there a diagnostic tool that will report what objects or what lines...

Just be careful with this approach. It includes non-word constituents, such as $500 or you might get a number like 159.500.3.24 or something like that.

Of course the down-side to the approach I...

Quote it with a space, like so:

grep " 500 " access

Note: No need to cat into a grep.

tr ',' ';' <filein | awk -F\; 'BEGIN{OFS=","} {print $1,$2,$3,$4*100+$5,$6*100+$7}'

Do you mean files that are exactly 2 months old today?

rm *.20090201

./myscript | awk '{ .... }'

Wow, I love it! Thanks cfa. All these years I've been doing:

for arg;do
stype=$(echo $arg|cut -b-3)
echo $stype
done

dash-v, e.g.:

grep -v foobar

would display all lines except those which contain "foobar" in it.

Thanks wempy. I missed the part about it only working with bourne/bourne-again in the initial post. Thanks.

Regarding the rest of your question, if it's always the case that you wish the commas were semi-colons in your new file, you could translate prior to your awk:
tr ',' ';' <csvfile | awk -F\; '{ ......

Yes, %i (and %d) are numeric. %s is character string (whereas %c is a single character).

What this is doing is inputing the csv file (separated by comma) and outputting all but the last field...

ksh.
This works fine on the command line:

$ D='$PWD'
$ PS1="$(hostname -s):$D> "
strawboss:/home/mlibby> cd /msa1/profiles/mlibby/ksh
strawboss:/msa1/profiles/mlibby/ksh>


The problem I'm...

As Jim said, scp (secure copy). It functions much the same as copy and even has the "preserve" option (dash-p) so the transfered files maintain their original date/time stamp, permissions, etc.

ls *.fits | grep -v "Zero\|zero" > objlist


List files in the current directory that end in .fits and DO NOT CONTAIN (i.e., -v) the word Zero or zero (case sensative), and write the results to...

Yes, I'm familiar with doing it that way. I was intrigued by the control character construct (e.g., \h \w etc.) and wanted to see that work. That is what I was having trouble with.

I did it on...

Orestis, that is why I mentioned you should look at the man pages for find, as I don't know exactly what your requirements are. And I think I said here is an example "roughly" what I think you may...

I entered the following, expecting to get "hostname:/current/path> " as a prompt (based on your post), but look what happened:


/msa1/agility/devel/bin> PS1="\h:\w> "
h:w> uname -s

h:w>...

Hi Corona. Thanks for your feedback. We tried LD but it really lacked intelligence for our purposes. For example, the numbers 2401 and 24 it reported as being 50% alike. Clearly by human eye you...

Look at the man pages for "find" command. Roughly what you're looking for:

#!/bin/bash
find $HOME -daystart -ctime 0 -type f >files_today.list # files modified today
find $HOME -daystart...

Followup: If your hostname is fully qualified (e.g. node.coname.com) you can do the following to just get node:
PS1="$(hostname|awk -F. '{print $1}'):/#>"

Also, if you want the current path as...

As illustrated above with the colon-slash-hash-greaterthan, like so:

PS1="$(hostname):/#>"

$Filename isn't known within awk. You could do this:
awk 'NR == 1 || substr($0,63,5) ~ /H... / && \
_++ == 1 { fn && close(fn); fn = Z "_" ++c; _ = 1 }
{ print > fn }' Z=$Filename $Filename

I have searched the internet (including these forums) and perhaps I'm not using the right wording.

What I'm looking for is a function (preferably C) that analyzes the similitude of two numerical...
