　　這里將講的是經(jīng)過挪用系統(tǒng) MACOS 下的 pbcopy、pbpaste 完成操作剪切板。

<span style="COLOR: rgb(169,169,169)">　　pbcopy takes the standard input and places it in the specified pasteboard. If no pasteboard is specified, the general pasteboard will be used by default. The input is

<span style="COLOR: rgb(169,169,169)">　　placed in the pasteboard as plain text data unless it begins with the Encapsulated PostScript (EPS) file header or the Rich Text Format (RTF) file header, in which case

<span style="COLOR: rgb(169,169,169)">　　it is placed in the pasteboard as one of those data types.

<span style="COLOR: rgb(169,169,169)">　　pbpaste removes the data from the pasteboard and writes it to the standard output. It normally looks first for plain text data in the pasteboard and writes that to the

<span style="COLOR: rgb(169,169,169)">　　standard output; if no plain text data is in the pasteboard it looks for Encapsulated PostScript; if no EPS is present it looks for Rich Text. If none of those types

<span style="COLOR: rgb(169,169,169)">　　is present in the pasteboard, pbpaste produces no output.

　　來看下簡略的運(yùn)用樣例，運(yùn)用 exec 函數(shù)是不是很簡略?呵呵!
