ToolHang Issue: xargs and zip -r Command in MacOS
In this article, we will discuss a common issue that arises when using the xargs and zip -r commands in MacOS, particularly when working with large files or directories. The problem occurs when the xargs command is used in conjunction with the -E and -a options, followed by the --format=zip option, and the command hangs or freezes.
Background
The xargs command is a powerful utility that allows users to build and execute command lines from standard input. It is often used in conjunction with other commands to process large numbers of files or directories. The zip command is a popular compression utility that is used to package and compress files and directories into a single archive file.
In MacOS, the zip -r command can be used with the xargs command to compress and archive multiple files or directories. However, when using the -E and -a options with the xargs command, followed by the --format=zip option, some users have reported that the command hangs or freezes.
Issue Details
The issue occurs when using the following command:
$ atool -E -a words.csv xargs --format=zip -n 1 -I % -P 4 zip -r words.zip %
In this command, the atool command is used to extract words from a compressed file, and the xargs command is used to pass each word as an argument to the zip -r command, which compresses and archives each word into a separate zip file.
However, when using this command, some users have reported that it hangs or freezes, and they are unable to stop it using the usual keyboard shortcuts.
Workaround
A workaround for this issue is to use the find command instead of the xargs command. The following command can be used as an alternative:
$ find words -maxdepth 1 -type f -exec zip words.zip {} \;
In this command, the find command is used to search for files in the words directory, and the -exec option is used to execute the zip command on each file, compressing and archiving it into the words.zip file.
The issue of the xargs and zip -r commands hanging or freezing in MacOS can be a frustrating problem for users. However, by using the find command as an alternative, users can still achieve the same functionality without encountering the issue.
