Function analysis of commands before and after xargs connection

Analysis of functions of xargs commands before and after xargs connection: find-typef-name & quot; * log & quot; -print | xargsls-l will be output after the command is executed for a period of time, that is, after the find is completed, the result is an echo to ls as the input, the usage of xargs is as follows: # find/-type f-name "*. log "-print | xargs ls-l # The output is generated after the command is executed for a period of time. that is, after the find operation is complete, the result is an echo to ls as the input, ls # find/-type f-name "*. log "-print | xargs-I {} ls-l {} # will have output immediately, that is, when one is found, there will be output; each result of find is executed n times as the input of a single ls. the-p parameter prompts you to confirm whether to execute the command. the-p parameter shows the differences between the preceding two commands. # Find/-type f-name "*. log"-print | xargs-I {}-p ls-l {} ls-l/configassist. log ?...

Therefore, when n is set to 1, the effect is the same as that of-I. In this way, some command parameters require a single input.
