一个sed例子 把文件aboutsed.txt中所有的单词"slow"换成"fast" $ sed s/slow/fast/g aboutsed.txt > output.txt [kevinz @stationxx kevinz ] $cat aboutsed.txt sed is a wonderful streaming editor.Its small size make it very slow. In fact,many people choose to use sed because it is so slow. [kevinz @stationxx kevinz ] $ sed s/slow/fast/g aboutsed.txt > output.txt [kevinz @stationxx kevinz ] $ cat output.txt sed is a wonderful streaming editor.Its small size make it very fast. In fact,many people choose to use sed because it is so fast. 在上面的例子中，s/命令告诉 sed在文件aboutsed.txt中搜索单词slow然后替换单词fast。命令后面的g告诉sed去替换文件中的所有匹配。
