如何复制或移动具有相同扩展名的多个文件? [英] How to copy or move multiple files with same extension?

问题描述

所以我试图将一堆具有类似扩展名的文件从/home/移动到/root/

So I am trying to move a bunch of files with similar extensions from /home/ to /root/

我试过的代码是

file copy /home/*.abc.xyz /root/

也试过了

set infile [glob -nocomplain /home/*.abc.xyz ]
if { [llength $infile] > 0 } { 
    file copy $infile /root/
}

没有成功.

推荐答案

由于不同的原因，您的两次尝试都失败了:

Your two attempts fail for different reasons:

1. file copy 或任何 Tcl 命令的参数中没有通配符扩展:file copy/home/*.abc.xyz/root/.这将查找文件名中带有文字 * 的单个源.

1. There is no wildcard expansion in arguments to file copy, or any Tcl command, for that matter: file copy /home/*.abc.xyz /root/. This will look for a single source with a literal * in its filename.

glob -nocomplain/home/*.abc.xyz 可以收集来源，但 glob 返回来源列表.file copy 要求每个源作为单独的参数传递，而不是单个参数.要将源文件的单个集合值扩展为多个单独的参数，请使用 Tcl 扩展运算符 {*}

glob -nocomplain /home/*.abc.xyz is ok to collect the sources, but glob returns a list of sources. file copy requires each source to passed as a separate argument, not a single one. To expand a single collection value of source files into a multiple separate arguments, use the Tcl expansion operator {*}

因此:

set infiles [glob -nocomplain *.tcl]
if {[llength $infiles]} {
   file copy {*}$infiles /tmp/tgt/
}
