Code:
irr= head -c 1  ./pump.txt
if [[ "$irr" == "0" ]]; then
        echo "!!!!!!!!!! Disabled"
else
        echo "Enabled"
fi

It does not work.


Ps, the file ./pump.txt is generated by the following commands:
either echo "1" > "./pump.txt" or
echo "0" > "./pump.txt"

Can you please help me?
Thanks,
daniele
Try
Code:
irr=$(head -c 1  ./pump.txt)

Note: No space between `='.

ZIPARCHIVE.ADDFILE(3)							 1						     ZIPARCHIVE.ADDFILE(3)

ZipArchive::addFile - Adds a file to a ZIP archive from the given path

SYNOPSIS
bool ZipArchive::addFile NULL (string $filename, [string $localname], [int $start], [int $length]) DESCRIPTION
Adds a file to a ZIP archive from a given path. PARAMETERS
o $filename - The path to the file to add. o $localname - If supplied, this is the local name inside the ZIP archive that will override the $filename. o $start - This parameter is not used but is required to extend ZipArchive. o $length - This parameter is not used but is required to extend ZipArchive. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
This example opens a ZIP file archive test.zip and add the file /path/to/index.txt. as newname.txt. Example #1 Open and add <?php $zip = new ZipArchive; if ($zip->open('test.zip') === TRUE) { $zip->addFile('/path/to/index.txt', 'newname.txt'); $zip->close(); echo 'ok'; } else { echo 'failed'; } ?> NOTES
Note When a file is set to be added to the archive, PHP will lock the file. The lock is only released once the ZipArchive object has been closed, either via ZipArchive::close or the ZipArchive object being destroyed. This may prevent you from being able to delete the file being added until after the lock has been released. PHP Documentation Group ZIPARCHIVE.ADDFILE(3)
