发信站: BBS 未名空间站 (Sat Oct 18 10:48:52 2008)
i am trying grep some text from a file then return some words:
grep "^>start" textfile.txt
but it always returns results one each line:
A
B
C
I want to have it as: A B C ..., so I tried to use sed:
grep "^>start" textfile.txt | sed -e 's/\n//'
it doesn't work, anyone knows how to solve this?
Thanks.
