linux find：通過xargs移動文件

Question

這應該如何解決？我下面a tutorial但我收到此錯誤：

$ find ~/Desktop -name 「*.jpg」 -o -name 「*.gif」 -o -name 「*.png」 -print0 | xargs -0 mv –target-directory ~/Pictures 
mv: cannot stat `–target-directory': No such file or directory 

*我感興趣的有關如何使用xargs的執行這個命令！

Answer 1

使用find和exec

$ find ~/Desktop -name "*.jpg" -exec mv '{}' /tmp/target/ \; -or -name "*.gif" -exec mv '{}' /tmp/target/ \; -or -name "*.png" -exec mv '{}' /tmp/target/ \; 

使用xargs的

$ find ~/Desktop -name "*.jpg" -or -name "*.gif" -or -name "*.png" | xargs -I SRCFILE mv SRCFILE /tmp/target/ 

Answer 2

我相信-target-directory應該是--target-directory，或只是-t。

Answer 3

你並不需要使用xargs，find可以在比賽中執行命令：

find ~/Desktop -name 「*.jpg」 -o -name 「*.gif」 -o -name 「*.png」 -exec mv \{\} ~/Pictures \; 

可以-exec後逃脫的分號\;之前發出命令。 \{\}被替換爲匹配的文件名。

從man find：

-exec command ;

Execute command; true if 0 status is returned. All following arguments to find are taken to be arguments to the command until an argument consisting of ';' is encountered. The string '{}' is replaced by the current file name being processed everywhere it occurs in the arguments to the command, not just in arguments where it is alone, as in some versions of find. Both of these constructions might need to be escaped (with a '\') or quoted to protect them from expansion by the shell. See the EXAMPLES section for examples of the use of the -exec option. The specified command is run once for each matched file. The command is executed in the starting directory. There are unavoidable security problems surrounding use of the -exec action; you should use the -execdir option instead.

注意，分號和{}必須進行轉義。
