Select lines based on character length
Hi,

I've got a file like this:

HTML Code:
22	22:35645163:T:<CN0>:0	0	35645163	T	<CN0>
22	rs140738445:20902439:TTTTTTTG:T	0	20902439	T	TTTTTTTG
22	rs149602065:40537763:TTTTTTG:T	0	40537763	T	TTTTTTG
22	rs71670155:50538408:TTTTTTG:T	0	50538408	T	TTTTTTG
22	rs147956527:27899116:TTTTTG:T	0	27899116	T	TTTTTG
22	rs112169882:26309326:T:TTTTTC	0	26309326	T	TTTTTC
22	rs112170669:29942398:T:TTTTTC	0	29942398	T	TTTTTC
22	rs148467612:32268721:TTTTTA:T	0	32268721	T	TTTTTA
22	rs71806779:32681699:TTTTTA:T	0	32681699	T	TTTTTA
22	rs7291429	0	17294251	G	T
22	rs2192431:17303596:T:G	0	17303596	G	T
22	rs175140	0	17306104	G	T
22	rs175147:17309362:G:T	0	17309362	G	T
22	rs12628206:17316990:T:G	0	17316990	G	T
22	rs7510758:17432482:T:G	0	17432482	G	T
22	rs4819923:17433210:T:G	0	17433210	G	T
And I need to print out lines that have only one character in columns 5 and 6. So, the output should look like this:

HTML Code:
22	rs7291429	0	17294251	G	T
22	rs2192431:17303596:T:G	0	17303596	G	T
22	rs175140	0	17306104	G	T
22	rs175147:17309362:G:T	0	17309362	G	T
22	rs12628206:17316990:T:G	0	17316990	G	T
22	rs7510758:17432482:T:G	0	17432482	G	T
22	rs4819923:17433210:T:G	0	17433210	G	T
So far, I've tried to use awk:

HTML Code:
awk '{print $5,$6}' in.file | awk 'length <3' > out.file
Unfortunately, (1) it is not that great because I do not get the whole line in the end and (2) it does not select the lines that I need.

Any help would be greatly appreciated!

Many thanks!

How about
Code:
awk '$5 $6 ~ "^..$"' file
22    rs7291429    0    17294251    G    T
22    rs2192431:17303596:T:G    0    17303596    G    T
22    rs175140    0    17306104    G    T
22    rs175147:17309362:G:T    0    17309362    G    T
22    rs12628206:17316990:T:G    0    17316990    G    T
22    rs7510758:17432482:T:G    0    17432482    G    T
22    rs4819923:17433210:T:G    0    17433210    G    T

This MAY fail if either field is empty and the other has two chars. Then, try
Code:
awk '$5 "," $6 ~ "^.,.$"' file

Or
Code:
awk 'length($5)==1 && length($6)==1' in.file > out.file
