可否确定使用灰色体显示的某一字数
我尝试了“-c”办法,但这种回报是,特定词的对应线数目在上。
例如,我有档案
某些词和配对 语言和配对 说 明
然后是另一个配对 说 明
“配对器”和“-c”选项在档案中穿透只剩2份。
注:这是对标准不ix的灰色指挥线的用处。
<代码>grep -o string file>将退回所有对应的探测事件。 然后,你可以做<条码>grep -o string file , . >-l
我认为,如果使用灰色——i-o string file , wc-l,就应当给你正确的产出,当你做什么——即——在档案中打脚?
You can simply count words (-w) with wc program:
> echo "foo foo" | grep -o "foo" | wc -w
> 2
