For example, the file command displays the types of files (executables, ASCII text, and so on); You can process the output so that it shows only the file name, and you now want to pass these names to the Ls-l command to see the timestamp.

1 Overview Xargs is a common command for UNIX and Unix-like operating systems. It is used to convert the parameter list into small segments and pass it to other commands to avoid the problem that the parameter list is too long.2 features (1) process space in the file/directory name Find.-name '*~ '-Print0 | xargs-0 RM has a problem. If the file or directory name contains spaces, there may be some problems,

Common Linux commands (20)-find xargs When you use the-exec option of the find command to process matched files, the find command passes all matching files to exec for execution. However, some systems have limits on the length of commands that can be passed to exec, so that an overflow error will occur after the find command runs for several minutes. The error message is usually "the parameter column is too long" or "parameter column overflow ". This

MPs queue and Xargs Command1. stdin, stdout, and stderr can use stdin, stdout, and stderr file pointers to access standard input, standard output, and error files for any newly generated process. Their types are all file * and belong to the C Runtime Library type. The kernel uses file descriptors to represent files. Stdin_fileno, stdout_fileno, and stderr_fileno are defined as 0, 1, and 2 respectively. Dup2 (srcfd, destfd) is used to copy the srcfd fi

The use of xargs commands in Linux is a filter for passing parameters to commands and a tool for combining multiple commands. It divides a data stream into small enough blocks to facilitate processing by filters and commands. In general, xargs reads data from an MPS queue or stdin, but it can also read data from the file output. The default xargs command is echo,

Then cat reads the text content to be processed from its standard input. This is equivalent to having a line character '--help ' in the Test.txt file and then running the cat test.txt effect.and Echo '--hel

When a matching file is processed using the-EXEC option of the Find command, the Find command passes all matching files to exec execution. However, some systems have a limit on the length of the command that can be passed to exec so that an overflow error occurs after the Find command runs for a few minutes. The error message is usually "parameter column too Long" or "parameter column overflow". This is where the Xargs command is used, especially with

The key to this command is that many commands do not support | Pipelines to pass parameters, and in daily work there is a need, so there is the Xargs command, Xargs is a filter to pass parameters to the command, but also a tool to combine multiple commands.
