I'm always concerned I might be abusing backticks within my scripts. A current script I'm writing has this for example:
stripscriptname=`echo $scriptname | sed 's/\(.*\)\..*/\1/'`
stripsearch=`echo $searchpattern | tr -d ' ,/'`
Both of these variables are set inside the script (in fact,... (2 Replies)
Hey all. Just a fast question, what is the technical difference between using back ticks and using xargs to perform a command?
Here's an example
Find /mydir -name *.conf |xargs rm
Vs
Rm 'find /mydir -name *.conf'
Is there a performance hit? I know they do the same thing but which is... (1 Reply)
Hi everyone. This is a bit of a perl/linux mixed question. I am trying to redirect STDOUT of chsh by using the following line of perl code.
system ("chsh -s /sbin/nologin $testing 1>/dev/null");
This should redirect STDOUT to /dev/null but it won't do that for some odd reason. Any ideas or... (6 Replies)

Hi all,
Here is my code:
my $x = `bash -c \" ls -l filename | awk '{print \$5}'\"`;
print "$x\n";
This will run the first part of the bash script but not the awk command. It therefore gives output of:
-rw-r--r-- 1 root root 13619200 2012-04-25 08:16 filename

I'm trying to make a dialog window that prints the output of grep that takes the output of find. Unfortunately my nested backticks don't work.
Here is the dialog window:

But I love my back-ticks - I know exactly how to escape them (after too many years) - I always seem to end unbalanced with ().
However, I shall take the hint. (One more trick for this dog... aka - not too old yet!) :);) (17 Replies)

get_font_range_end
get_font_range_end(3alleg4) Allegro manual get_font_range_end(3alleg4)NAME
get_font_range_end - Returns the last character of a character range in a font. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
int get_font_range_end(FONT *f, int range)
DESCRIPTION
This function allows you to find out the index to the last character of a character range for a font. You can pass -1 for the range parame-
ter if you want to know the start of the whole font range, or a number from 0 to (but not including) get_font_ranges(f) to get the start of
a specific character range in the font. You should check the start and end of all font ranges to see if a specific character is actually
available in the font. Not all characters in the range returned by get_font_range_begin(f, -1) and get_font_range_end(f, -1) need to be
available! Example:
printf("The font has a character range of %d - %d
",
get_font_range_begin(font, -1),
get_font_range_end(font, -1));
RETURN VALUE
Returns the last character in the font range, or -1 if that information is not available.
