oh, my fault--I see whatchu mean now. I overlooked that...I was wondering why you posted that; just a minor oversight on my part. The way you explained it previously was kinda ambiguous.

Thanks...

I know that, the sample of code I posted was copied from the interactive command-line, hence single-% denoted variables. I've been reading the help file for "for /?" and it's pretty worthless and...

I'm wondering if any of you could lend an assist with a small problem.

First, I'm under the impression I need to use Delayed Environment Variable Expansion (DEVE), based on other things I've read...

I was reading that because each segment of a pipeline is handled inna child shell of the parent, that setting multiple variables using output from preceding segments of a pipeline into a read command...

get a list of each interface

i.e. do an ifconfig -a, then grep for the common keyword denominating each virtual interface

extract the part of each result from grep, possibly using something...

Hey, guys!

Trying to research this is such a pain since the read command itself is a common word. Try searching "unix OR linux read command examples" or using the command substitution keyword....

Thanks, Jim!

I found this same article and came back here to update anybody else who might be seeking similar information. Good find!!

Thanks to everybody else who provided info too--you...

lemme rephrase...

what keywords should I research to find more about the use/features/options of the ":#:#" convention??

e.g. does that feature have a name?!

You know variable expansion...

hey, man--where can I find documentation on this li'l procedure?! I mean, what are the underpinnings--what made that work?! What function of UNIX allowed you to do that? Is it built in to the echo...

Hey, geniuses of the world (no--facetious is NOT the word of the day;))!

I was wondering if there's a way to extract a specific portion from a string of characters in UNIX/LINUX. Give me the...

Panyam,

Thanks for your response. I wasn't really looking to embed a newline after the column headers though.

I was interested in double-spacing the rows of data.

Actually,
I was in Csh...

Morning, people!

I'd like to call upon your expertise again, this time for a sed endeavor.

I've already searched around the forums, didn't find anything that helped yet.

Pludi,

That was educating. Particularly when you underscored that find recognized the current working directory as a directory itself and pruned itself.

So comparing . (cwd) vs ./* (contents...

So I fell out of my chair when I realized how ./* made the world of difference. By the way, this performed exactly what I originally intended. Pludi, YOU'RE THE MAN!! Anybody who tells you...

I know one of the more seasoned veterans probably opened this thread looking for their chance to refer me to the site's search feature and let me tell you.

I'VE LOOKED!!!! And I didn't find...

by the way, it is a known caveat that you can't use read in a pipeline, because of the way read is called in a subshell. Effectively the values stored to the named variables in read will only be...

I know there are caveats about using read in pipelines because read is treated by a subshell. I know this but I can't think of any way to accomplish this regardless, I'm still a rookie.

I hope...

Lakris,

Thanks for the explanation. I had done some reading and I understood what printf was intended to do, but I didn't realize that the $x after the quotes was intended to be the input for...

context:

while reading tutorial on the read command, one of the first examples, demonstrating its use, follows as such:

$ x=abc ; printf "x is now '%s'. Enter new value: " $x ; read x
...

error:
Unmatched '


thanks for your input though. If you don't mind explaining, could you go into detail of the structure of this statement and why you did that.

I'm still trying to...

so I discovered some info on this site AFTER I posted, I guess this isn't uncommon using the suggested links for related posts.

anyway,

syntax I got for accomplishing everything I wanted ended...

I want to accomplish this in sh, however if the capability exists only in other shells elsewhere that's acceptable.
