It depends on where you get the input string from and what the separators are. If | is in the set it's tricker, but in general, to split on a set of characters, you can use set -- with IFS set to the token splitting characters. That's what I continue to suggest.
I don't know how to make it any clearer than that. Now "see" is in $1, "hear" is in $2, "touch", in $3, and "smell" in $4. I think that satisfies your requirement.
If you are reading an input string from the terminal then you can add | to the set of splitting characters no problem, but you can't use it directly in a script because it's already a command separator (for setting up pipelines, no less).
I have a problem that I want to insert and delete some chars in the middle of a file. fopen() and fdopen() just allow to append at the end.
Is there any simple method or existing library that allow these actions? Thanks in advance.:confused: (7 Replies)

I want to create a temp file which is named based on a search string. The search string may contain spaces or characters that aren't supposed to be used in filenames so I want to strip those out.
My thought was to use 'tr' with but the result is the opposite of what I want:

I tried to replace the following in vi:
old: 'e/thesis/pp/zones/zones'
new: 'd/so162/fix/pp'
For that, I used: :%s/e/thesis/pp/zones/zones/d/so162/fix/pp/g

I wrote myself a small little shell script to clean up a file I have issues with. In particular, I am stripping down a fully qualified host/domain name to just the hostname itself. The script works, but from a performance standpoint, it's not very fast and I will be working with large data sets.

CTYPE_CNTRL(3) 1 CTYPE_CNTRL(3)ctype_cntrl - Check for control character(s)SYNOPSIS
bool ctype_cntrl (string $text)
DESCRIPTION
Checks if all of the characters in the provided string, $text, are control characters. Control characters are e.g. line feed, tab, escape.
PARAMETERS
o $text

RETURN VALUES
Returns TRUE if every character in $text is a control character from the current locale, FALSE otherwise.
EXAMPLES
Example #1
A ctype_cntrl(3) example
<?php
$strings = array('string1' => "
", 'string2' => 'arf12');
foreach ($strings as $name => $testcase) {
if (ctype_cntrl($testcase)) {
echo "The string '$name' consists of all control characters.
";
} else {
echo "The string '$name' does not consist of all control characters.
";
}
}
?>
The above example will output:
The string 'string1' consists of all control characters.
The string 'string2' does not consist of all control characters.

ues have 256 added in order to allow characters in the Extended ASCII range). Any other integer is interpreted as a string contain-
ing the decimal digits of the integer.
