UNIX for Dummies Questions & Answers

Thanks ,

it works with input file :

[565342:00002-00001] 17/04/2008 06:17:09
> [565342:00002-00001] 17/04/2008 06:17:09
[983254:00002-00001] 17/04/2008 00:00:02

but doesn't if the input file contains more than 3 fields like the following :

[565342:00002-00001] 17/04/2008 06:17:09 sfsfsfsfsfsdfsfsf
> [565342:00002-00001] 17/04/2008 06:17:09 fsfsfsdfdsfsfdsfsf
[983254:00002-00001] 17/04/2008 00:00:02 sfsfdsfdsfdsfdsf
> [983254:00002-00001] 17/04/2008 00:00:02 sfdsfdsfdsfdsf

we get :

[565342:00002-00001] 17/04/2008 06:17:09 sfsfsfsfsfsdfsfsf
> [565342:00002-00001] 17/04/2008 06:17:09 fsfsfsdfdsfsfdsfsf
[983254:00002-00001] 17/04/2008 00:00:02 sfsfdsfdsfdsfdsf

i don't understand why !

The previous script checks the number of fields and assumed that the last field is the timefield so it won't work if you increase this number.
Try this one:

Code:

awk '
/^>/ && substr($4,1,2) > "05" {print;next}
substr($3,1,2) > "05" {print}
' file

Thanks ,

well it doesn't work :

cat csl2.txt

[565342:00002-00001] 17/04/2008 06:17:09 sfsfsfsfsfsdfsfsf mgfmlgkjgmldskj
> [565342:00002-00001] 17/04/2008 06:17:09 fsfsfsdfdsfsfdsfsf mdfjdsmlfls
[983254:00002-00001] 17/04/2008 00:00:02 sfsfdsfdsfdsfdsf sfldsjfldskfjslkfj
> [983254:00002-00001] 17/04/2008 00:00:02 sfdsfdsfdsfdsfs lkgfjdslksjdfl

awk '/^>/ && substr($4,1,2) > "05" {print;next} substr($3,1,2) > "05" {print}' /users/notes01/csl2.txt

[565342:00002-00001] 17/04/2008 06:17:09 sfsfsfsfsfsdfsfsf mgfmlgkjgmldskj

> [983254:00002-00001] 17/04/2008 00:00:02 sfdsfdsfdsfdsfs lkgfjdslksjdfl

the lines may begin with "[" whether "> "

i still have line with "00" hour

it's just an extract of the input file which is more than 100Mo long

Oops, forgot something, this should do it:

Code:

awk '
/^>/ && substr($4,1,2) > "05" {print;next}
/^>/{next}
substr($3,1,2) > "05" {print}
' file
