鬼脚本 |不可恢复的错误，退出代码 1

2022-01-24 00:00:00 debian php apache ghostscript

我有一个用来合并 PDF 的 shell 脚本，在今天之前，它似乎运行良好.

I have a shell script that I've been using to merge PDFs, and prior to today, it seems to have been working fine.

现在，当我跑步时，我收到以下消息:GPL Ghostscript 9.06:不可恢复的错误，退出代码 1

Now when I run, I get the message: GPL Ghostscript 9.06: Unrecoverable error, exit code 1

它会生成一个空白 PDF，而不是合并的 PDF.这是我的代码:

It produces a blank PDF instead of the merged PDF. Here is my code:

<?php

$pdf1 = "file_1.pdf";
$pdf2 = "file_2.pdf";


$fileArray= array($pdf1,$pdf2);


$datadir = "/usr/pdf_merge/merged";
$outputName = $datadir."merged_new.pdf";

$cmd = "gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=$outputName ";
//Add each pdf file to the end of the command
foreach($fileArray as $file) {
    $cmd .= $file." ";
}
$result = shell_exec($cmd);

有什么想法可能是错的吗?

Any ideas what could be wrong?

我正在使用 Debian 运行 Apache.

I'm running Apache with Debian.

谢谢

推荐答案

把这个$cmd改成

$outputName = "merged_new.pdf";
$cmd = "cd ".$datadir." && gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=$outputName ";"
