Some comments on top of what Don Cragun said:
awk -F "," keys.txt '{print $1}' can't possibly work (reverse order of arguments) and is superfluous - you could simply read IFS="," key_ REST; ... < keys.txt
grep -v ",-1$" is pointless as (at least in the samples given) there's no line ending in "-1"
And, for each line in keys.txt times each matching line in file1.txt, you run 10 processes to extract a few fields - no surprise that is slow.

PharData::extractTo - Extract the contents of a tar/zip archive to a directory

SYNOPSIS
bool PharData::extractTo (string $pathto, [string|array $files], [bool $overwrite = false]) DESCRIPTION
Extract all files within a tar/zip archive to disk. Extracted files and directories preserve permissions as stored in the archive. The optional parameters allow optional control over which files are extracted, and whether existing files on disk can be overwritten. The sec- ond parameter files can be either the name of a file or directory to extract, or an array of names of files and directories to extract. By default, this method will not overwrite existing files, the third parameter can be set to true to enable overwriting of files. This method is similar to ZipArchive.extractTo(3). PARAMETERS
o $pathto - Path to extract the given files to o $files - The name of a file or directory to extract, or an array of files/directories to extract o $overwrite - Set to TRUE to enable overwriting existing files RETURN VALUES
returns TRUE on success, but it is better to check for thrown exception, and assume success if none is thrown. ERRORS
/EXCEPTIONS Throws PharException if errors occur while flushing changes to disk. EXAMPLES
Example #1 A PharData.extractTo(3) example <?php try { $phar = new PharData('myphar.tar'); $phar->extractTo('/full/path'); // extract all files $phar->extractTo('/another/path', 'file.txt'); // extract only file.txt $phar->extractTo('/this/path', array('file1.txt', 'file2.txt')); // extract 2 files only $phar->extractTo('/third/path', null, true); // extract all files, and overwrite } catch (Exception $e) { // handle errors } ?> SEE ALSO
