Text file manipulation

Hi,
I need to remove lines from a text file that are less than certain length in UNIX. For example, test.txt file contains the following lines:

abcdefghijklmnopqrstuvwxyz.
123456789009876543211234567
This line to be removed.
zyxwvutsrqponmlkjihgfedcba.

The length of each line is supposed to be 27 characters. I need to remove 3rd line which is less than 27 characters.
Pls. help.

Thanks,
Suresh

awk ' { if ( length($0) >= 27 ) print $0; }' test.txt

Just another syntax for the awk command :

awk 'length >= 27' text.txt
