xargs

Xargs is a filter that can pass parameters to a command, and a tool that combines multiple commands, dividing a 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

1. IntroductionThis command is available because many Linux commands do not support piping parameters, such asFind/sbin-perm +700 | Ls-l This command is wrong.Find/sbin-perm +700 |xargs Ls-l This is the right thing.Normally the Linux command can be | connected to the end, and the previous command's stdout is connected to the stdin of the next command. However, some commands, such as, and ls rm so on, are accepted from the command line parameters. This

(1) The Find command is based on the attributes of the file, such as file name, file size, owner, owning group, whether it is empty, access time, modification time, etc.(2) grep is a search based on the contents of the file, and each line of the file is matched in a given pattern (patter).(3) The Find command passes the matched file to the Xargs command, and the Xargs command takes only a subset of the file

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. in this way, after the find command is run for a few minutes, an overflow error will occur: LinuxFind The error message is usually "the parameter column is too long" or "parameter column overflow ". This is the use of the xargs
