In fact I saw the use of getopts for switches in the book "KornShell Programming Tutorial"...

Hello there,



Thanks for your answer.



Actually, the only reason that I wrote those options in my code was due to
what I read in 'man 2 mount'


#include <sys/mount.h>

Dear all,


Inside a C program, I want to open a very big file (about 12 GB) in order to read its
content. Here is the code:

Dear pludi


Thank you very much for your help. Your solution solved my problem.

Dear all,


I use perror in order to print an error message to the standar error. For example
if a C program is called without its two necessary command line parameters

Hello there,

I think that the following KornShell script does the job


#!/bin/ksh

function substring
{
TOKEN=$1
LENGTH=${#TOKEN}
COUNTER=0
typeset -L1 CURRENT_CHARACTER...

Hello there,

It may seem a trivial question, but did you try to see whether the grep command itself does the job? (or maybe I didn't understand the exact output form that you're looking for)

:)

Hello there,

Your script accepts three command line options -l -h and -g and each of these options requires an argument. The case inside checks the validity of the inserted values. You will run...

When you say the second file is fixed line, do you mean a single line in the file? because if it is the case, I don't really see what is the point for using a second file, you could just assign its...

Ok, try this new version, it must work much faster than the precedent version


#!/bin/ksh

IFS='
'

FINAL_RESULT=""

VARIABLE1="var1 first line
var1 second line
var1 third line
var1...

Did you run my script to see the result? :mad:

Well in this case, try this


#!/bin/ksh

# The fact that we set IFS only on new line is that in this question
# space and tabs are not considered as delimiters, only new lines
IFS='
'

Assuming that you don't explicitly write \n at the end of each line, I think the following KornShell script does the job.


#!/bin/ksh

# The fact that we set IFS only on new line is that in...

Maybe what I'm asking seems a bit trivial, which of the following is the format of your data?


VARIABLE="line1
line2
line3

or


VARIABLE="line1\n
line2\n
line3\n
...
What I mean is...

Hello there,

I didn't understand exactly your problem, you said


and then you say



So finally time is it important or not?



If all of those files have the same pattern, can you...

Yes, you're right, I didn't know that, thanks for this remark :D

Actually both " " and ' ' turns off the special meanings of the meta characters, except that " " doesn't do that for \ $ ' and ".

But from the number of arguments interpretation point of view, at...

Yes, you are right about the fact that \n is eliminated from the end of the input by the read function. However even after running
