correct syntax for using "grep regex filename" ?
I'm trying to grep a long ls by looking at the beginning of each filename for example:
Many files begin with yong_ho_free_2005... Many files begin with yong_ho_2005... I can't just use "grep yong_ho" otherwise It'll display both files. So I'm trying to use a regex but my syntax is wrong. ls -al | grep '^yong_ho_[1-9]' This displays no matches. Anyone know what I'm doing wrong? It works if I remove the ^ carat... How come I can't anchor it? Last edited by yongho; 06-13-2005 at 03:32 PM.. |

The problem is that no line starts with yong, when using the long listing the file name is the last field on the far right... Dont use the ^ in your listing it is irrelevant.
ls -al | xargs| grep 'yong_ho_[1-9]' |
