Xargs command

Xargs is a filter that passes parameters to the command, and is also a tool for combining multiple commands . It divides a data stream into small enough chunks to facilitate the processing of filters and commands. Typically, Xargs reads data from a pipe or stdin, but it can also read data from the output of a file. The default command for Xargs is echo, which means that the input passed to Xargs by the pipeline will contain line breaks and whitespace, but with xargs processing, line breaks and whitespace will be replaced by spaces.

　　Xargs is a powerful command that captures the output of a command and then passes it to another command.

In simple terms, the "|" is usually Use the output of the previous command as input to the latter command.

Example 1:

When you use the RM command to delete many files, you may get an error message: "/bin/rm Argument list too long–linux". You can use Xargs to avoid this problem.

Find ~-name *.log '-print0 | xargs-0 rm–f

Example 2:

# find/etc-name "*.conf" | Xargs ls–l
