Maybe I will give a sample script
#!/bin/sh
check() {
if [ ! -d ${1} ]; then
echo "${1} is not a dir"; exit 1
fi
echo dir
}
home=/u4/k
check home
----------------------
1) if /u4/k does not exist then the desired output is -
home
home (/u4/k) is not a dir
The idea is to give in a message both the variable and its value. So this check
can be made generic. In windows, this can be achieved.
Thanks,
Sonal

LEARN ABOUT PHP
php_check_syntax
PHP_CHECK_SYNTAX(3) 1 PHP_CHECK_SYNTAX(3)
php_check_syntax - Check the PHP syntax of (and execute) the specified file
SYNOPSIS
bool php_check_syntax (string $filename, [string &$error_message])
DESCRIPTION
Performs a syntax (lint) check on the specified $filename testing for scripting errors.
This is similar to using php -l from the commandline except that this function will execute (but not output) the checked $filename.
For example, if a function is defined in $filename, this defined function will be available to the file that executed php_check_syntax(3),
but output from $filename will be suppressed.
Note
For technical reasons, this function is deprecated and removed from PHP. Instead, use php -l somefile.php from the commandline.
PARAMETERS
o $filename
- The name of the file being checked.
o $error_message
- If the $error_message parameter is used, it will contain the error message generated by the syntax check. $error_message is
passed by reference.
RETURN VALUES
Returns TRUE if the lint check passed, and FALSE if the link check failed or if $filename cannot be opened.
CHANGELOG

| 5.0.1 | |
