Yes, but:
fl[0-9] (called "Pathname Expansion / Pattern Matching") expands to EXISTING files that match the pattern, fl{0..9} (called "Brace Expansion") yields all strings unconditionally:
echo...

They are a couple examples of ways you could call multiple files (even more than just two) at the command line, courtesy of the shell, without writing one by one.

fl[0-9] would expand to fl0 fl1...

perl -ne '$.=1 if $ARGV ne $previous; print "$. in $ARGV: $_" if /\d\d/; $previous=$ARGV' fl[0-9] fl1{0..9}

Here is sample code using dup() and dup2()- I copied this from somewhere years ago:

#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <unistd.h>

int main(int argc, const...

(?:^[^\r\n\{]*;?[\s]+){0,10}
(){0,10} # a grouping that could repeat from 0 to 10 times max
?: # do not capture this group (do not save in memory to use later)
^ # match start of the line...

Unfortunately I must disagree. For your purposes, they amount to #define's without the mess. They don't vanish in precompilation, but they do vanish in a later phase of compilation, values set and ...

Designated inits in gcc actually work with enums! This might give you something close to what you wanted...

#include <stdio.h>

enum { A, B, C };
enum { D=5, E, F };

const int lookup[256]={...

Because 1 isn't 0? :confused: enums are just integers, their definitions don't change the laws of mathematics.

I think you might be confused about what an enum is. They're integers, pure and...

Thanks Anchal. I am using write_row() after getting the row from the database . In the complete worksheet I have several columns which I need as integers. Is there a way I can make particular column...

Only two things I can suggest:
1. IFS variable was changed somehow.
2. It's zsh shell.

Try this:#!/bin/csh -f
echo " -- starting $0 --"
echo " .. before executing bash-code : "

/bin/bash <<"#END"
pair=123-456
aRID=${pair%-*}
iRID=${pair#*-}
echo " aRID=$aRID;...

How about this:$ perl -de 0

You'd also be interested in exploring cpp ; Its the C pre Processor , available on most UNIX systems. However, I have used it mostly on my Linux ststems only ;)

Just run the command:

$ cpp...

You need the "-P" switch which stops acc after the preprocessing stage and produces a file with the same prefix as the source filename but with a ".i" extension.

Pass the `-E' flag to gcc, which tells gcc to stop after the preprocessing stage. You should probably use a .i file extension (e.g. `gcc program.c -E -o program.i') since that's the standard for C...

There are a few things wrong.

You aren't declaring main() to return an int, although the compiler is probably taking care of this for you.

main() is not returning a value.

rt is not the...

First, you need to read the man page on system(3). The return value is of the format returned by wait(2). Thus, you need to feed that into the WEXITSTATUS macro to get the actual return value.

I am using the below script in a production machine in a backup script and it works pretty well, on 1st of Jan and 1st of March (leap years) it works correctly, considers leap year well, try it

#!...

It's real DATA ANALYSIS!

Why are you using "ls -l" if all you want is the names? Try ls -1.. That will simplify things for you... As for the special characters, get used to "od" Octal Dump.......

Hi,
I managed to get that working using exec & pipes.The following is the script which i hope to work for you as well,

#!/bin/bash

Helo.

sed 's/^M//g' input_file > output_file

will do the job, but to get the "correct" "^M" use:
"control+v" followed by "control+m" key combinations.

Regards.

Thanks for the swift response guys - much appreciated.

Thestevew was right - I was misunderstanding the vi 'set list' option, so thanks for putting me straight.

I eventually came up with a...

in vi you can replace all ^M characters with command
:%s/^M//g

(Note that to type ^M in vi type Ctrl-V Enter)

I realise that this note may be offensive for vi users :)

In vi, use
:set list
and you can do
:set nolist
to get back to normal.
