Says google :s

Personally I prefer Nokia due to free licensing for commercial products using QT. But then, I'm more than likely a minority. I have no predictions, except that soon this little...

pfft, stupid plus sign.

Thanks guys.

Hey, I need to use the date command for arguments to a C++ program. But i need the format to be in %d%m%y, the manual for date doesn't actually say how to format, it just lists the formats. So i...

why? bourne shell accomplishes this easily. It was the assignment I did back in November. printf for field widths, functions for each task typically using grep. Test for all command line args, and a...

100 view and not a single idea :(, Bump!

I did an assignment for sh scripting back in november, and I found it quite fun learning. I would like to retain this knowledge as I'm pretty sure it was my only scripting assignment, from now on in...

EDIT: woops didn't see there was page2

perfect thanks just had to change all my echo statements using variables to printf. some were already in printf which is why the error were only occurring on some variables.

I'm thinking that maybe I need to just stick the arguments into a temp $VAR or file
and then convert back to OLDIFS at bottom of loop and then execute function using the var/file as arguments,...

I understand that, but that is only in the case of while IFS=: read ... what I am saying is I have been told to do it differently in the format of:

OLDIFS=$IFS
IFS=":\n"
I am unsure why...

or diff... 'man diff ' , I'm pretty sure there's a way to only output differences.
EDIT: probably not so useful...even
$diff --suppress-common-lines file1 file2
still outputs the line numbers...

there's a number of different ways you can do this, one example is cut/paste
cut f1 file > tmp1; cut f2 file > tmp2; cut f3 file > tmp3; etc etc
paste tmp1 tmp2 tmp3 tmp4 > file
rm -f tmp*
...

cat "nothing" | to awk.....

dammit beat me to it by 3 seconds...!

I know there's a large number of posts on this, I have read a number of them. But unable to find specifics.

Scrutinizer showed me a nice trick using IFS in a while loop in a BASH script, however...

woops.. misread,

thanks again

Thanks again scrutinizer (and others) you have definately taught me a lot over the last few days. Only have only last "ambiguous redirect" error occurring which I should be able to figure out and...

double post, this site has been screwy today ^_^

EDIT: ok, nevermind I just got it, testing for a line in a file.... which is true so we delete. duh...

EDIT: why does my head always feel like...

I don't really get that... the -q option states: Quiet; do not write anything to standard output. Exit immediately with zero status if any match is found, even if an error was detected. Also see the...

hmmm woops
I just retested to make sure I didn't have a typo or something.
and realized the first time round i never actually tested to make sure i could delete an invalid item. It works we just...

that didn't work for me

do you mean after I grep the line?

I was thinking I could test the string is non-zero eg.


if [ -z (grep "${1}${2}" $dbfile) ]
then
echo "Error:not deleted:product does not exist in...

Hello ...again.
I am stuck on this part, I have a loop with processes an operations file.
and calls different functions depending on what is in loop, which processes a database file...


#so far...

something is wrong, I can read every post except mine. Very weird, and extremely anoying I can see replies to my post but can't view them, instead it keeps trying to save the page and open it from...

man expr, expr evaluates mathematical expressions in sh scripts.

I have this code, I thought it would automatically know the args sent to script when called from shell. But it seems to not see any...


main script:

. args
. errors
. opt
. clean
