[SOLVED] sed match none greedy

ted_chou12 · 02-19-2013, 02:46 AM

Hi, how do I match:

Code:

2005-12-15+19:16:32.0000000000  /mnt/main//GUNxSWORD(Music)/13 Bitter Dream
2005-12-15+19:16:32.0000000000  /mnt/maerawerawer/GUNxSWO RD(Music)/12 Hearts Together

I wish to use sed to replace the long string of numbers in the front. Such that:

Code:

/mnt/main//GUNxSWORD(Music)/13 Bitter Dream
/mnt/maerawerawer/GUNxSWO RD(Music)/12 Hearts Together

are the results, this seems like that I only want to match the first space and don't want the match to get the 2nd or spaces after words.
I've tried:
sed 's:^.*\s::i'
but it doesnt work.
Thanks,
Ted

The regular expression .*\s matches all the characters until the last space (spaces included). You have to exclude the space from the character list in order to match all the chracters until the first space, e.g.

Code:

sed 's/^[^ ]* //' file

Not sure about matching only the first space and not the second one. According to the desired output you should match any number of spaces after the first string, that is

Code:

sed -r 's/^[^ ]* +//' file

Hope this helps.

If I understood your requirement correctly, then you can:

Code:

~$ awk -F" " '{print $1,$2,$3,$4,$5}' infile.txt

thanks for everyone's help here. colucix's first code seems to got me very close:

Code:

2003-09-29+08:39:08.0000000000  /mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/04 - Seishun In the Starlight.mp3
2003-09-29+08:29:12.0000000000  /mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/02 - Go Go Goal.mp3
2003-09-29+08:08:50.0000000000  /mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/03 - Promise.mp3
2003-09-29+08:07:28.0000000000  /mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/05 - Love and Chasing.mp3
2000-06-13+18:26:45.2655000000  /mnt/main/media/music/英文歌/how do i breathe.mp3

gave me

Code:

Boys OST - Love & Chasing/01 - Shake It Up.mp3
Boys OST - Love & Chasing/04 - Seishun In the Starlight.mp3
Boys OST - Love & Chasing/02 - Go Go Goal.mp3
Boys OST - Love & Chasing/03 - Promise.mp3
Boys OST - Love & Chasing/05 - Love and Chasing.mp3
do i breathe.mp3

but I wish to get the space prior toe that:

Code:

/mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/04 - Seishun In the Starlight.mp3
/mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/02 - Go Go Goal.mp3
/mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/03 - Promise.mp3
/mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/05 - Love and Chasing.mp3
/mnt/main/media/music/英文歌/how do i breathe.mp3

Thanks, Ted

sorry my bad, the :

Code:

2003-09-29+08:39:08.0000000000  /mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/04 - Seishun In the Starlight.mp3
2003-09-29+08:29:12.0000000000  /mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/02 - Go Go Goal.mp3
2003-09-29+08:08:50.0000000000  /mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/03 - Promise.mp3
2003-09-29+08:07:28.0000000000  /mnt/main/media/music/主題曲/灌籃少年/Dear Boys OST - Love & Chasing/05 - Love and Chasing.mp3
2000-06-13+18:26:45.2655000000  /mnt/main/media/music/英文歌/how do i breathe.mp3

is not a space but a tab /t thus:
sed 's:^.*\t::g'
simply did the trick, but thanks!
