Can someone explain the difference between backticks and system when
evaluated in these if statements:
sub getDate {
print "start date\n";
if ( system("/bin/date") ) {

exit(2);
}
print "finish date\n";
}
Returns the following:

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)
Input file:

'data_10'
'data1311'

Desired output:

Can I know how to remove back tick"'" in a file?
Many thanks for advice. (3 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)

gb18030
GB18030(5) BSD File Formats Manual GB18030(5)NAME
gb18030 -- GB 18030 encoding method for Chinese text
SYNOPSIS
ENCODING "GB18030"
DESCRIPTION
The GB18030 encoding implements GB 18030-2000, a PRC national standard for the encoding of Chinese characters. It is a superset of the older
GB 2312-1980 and GBK encodings, and incorporates Unicode's Unihan Extension A completely. It also provides code space for all Unicode 3.0
code points.
Multibyte characters in the GB18030 encoding can be one byte, two bytes, or four bytes long. There are a total of over 1.5 million code
positions.
GB 11383-1981 (ASCII) characters are represented by single bytes in the range 0x00 to 0x7F.
Chinese characters are represented as either two bytes or four bytes. Characters that are represented by two bytes begin with a byte in the
range 0x81-0xFE and end with a byte either in the range 0x40-0x7E or 0x80-0xFE.
Characters that are represented by four bytes begin with a byte in the range 0x81-0xFE, have a second byte in the range 0x30-0x39, a third
byte in the range 0x81-0xFE and a fourth byte in the range 0x30-0x39.
