I have to solve some exercises in Korn Shell, but i'm having some problems. For example:
Write a korn shell script with an alfanumeric string as argument. The script lists the file's names in the current directory that contain the given string as substring and that can be read and written.
I can read the string from standard input and also print on screen the file's names which contain the string, but only if use the name of the file as parameter. I can't search the string among all the regular files in my directory and i have no idea on how to filter files basing on permissions. This is my code:
stringhe.rtf is a text file with some random strings created by me.

I have this Korn shell script that runs via a cron entry. It runs in a loop "watching" a specific file system for files with a certain name. The file system that it is watching is an upload file system for an FTP server. When files that are the correct name come in, it takes the extension of the... (1 Reply)

LEARN ABOUT PHP
ereg_replace
EREG_REPLACE(3) 1 EREG_REPLACE(3)ereg_replace - Replace regular expressionSYNOPSIS
string ereg_replace (string $pattern, string $replacement, string $string)
DESCRIPTION
This function scans $string for matches to $pattern, then replaces the matched text with $replacement.
Warning
This function has been DEPRECATED as of PHP 5.3.0. Relying on this feature is highly discouraged.
PARAMETERS
o $pattern
- A POSIX extended regular expression.
o $replacement
- If $pattern contains parenthesized substrings, $replacement may contain substrings of the form digit, which will be replaced
by the text matching the digit'th parenthesized substring; will produce the entire contents of string. Up to nine substrings
may be used. Parentheses may be nested, in which case they are counted by the opening parenthesis.
o $string
- The input string.
RETURN VALUES
The modified string is returned. If no matches are found in $string, then it will be returned unchanged.
EXAMPLES
For example, the following code snippet prints "This was a test" three times:
Example #1
ereg_replace(3) example
<?php
$string = "This is a test";
echo str_replace(" is", " was", $string);
echo ereg_replace("( )is", "\1was", $string);
echo ereg_replace("(( )is)", "\2was", $string);
?>
One thing to take note of is that if you use an integer value as the $replacement parameter, you may not get the results you expect. This
is because ereg_replace(3) will interpret the number as the ordinal value of a character, and apply that. For instance:
Example #2
ereg_replace(3) example
<?php
/* This will not work as expected. */
$num = 4;
$string = "This string has four words.";
$string = ereg_replace('four', $num, $string);
echo $string; /* Output: 'This string has words.' */
/* This will work. */
$num = '4';
$string = "This string has four words.";
$string = ereg_replace('four', $num, $string);
echo $string; /* Output: 'This string has 4 words.' */
?>
Example #3
Replace URLs with links
<?php
$text = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]",
'<a href="\0">\0</a>', $text);
?>
NOTES
Note
As of PHP 5.3.0, the regex extension is deprecated in favor of the PCRE extension. Calling this function will issue an E_DEPRECATED
notice. See the list of differences for help on converting to PCRE.
Tip
ereg_replace(3) is deprecated as of PHP 5.3.0. preg_replace(3) is the suggested alternative to this function.
