[Solved] Length of each string
Hi

I have a file which has sequences which look like this

Code:
>String1
aqwertrtrytytyuuijhgddfghhhghhgjhjhhsswekrkmygppdslxmvbnhkwqalldrtjbllnlnlnnnvc
>String2
qwwerrtyuiopasdfghjmnbvfklzxerbvcwghjjkoowwqerrtggbddqsdfgaqwcxzakjtyugfsdefrtgyhujiknbbbbcdcdcxsxsx zxzxcvcfcdcg
>String3
rtyhujrfedwsqavfbgnhmjklopoiuytiuytrewqxszavfbgnhmjkjgdaaarftgwqwqsxddfcazxshjklopute
...

>String120..

Is there a way I could find the length of each string?

For an example:
(If I need to count length of STRING 1 ,I need to begin from
Code:
>String1.........................

and stop at " > " of string2)

Could anyone advise?

You have a carriage control (newline character) after >String1. This will not count that character.

Code:
awk 'NR%2==1 {keep=$0; next}
        NR%2==0 {print keep, length(keep $0)}  ' inputfile

Doesnt the awk command you mentioned count the length per line?
I was wondering if there is a way to count length of a particular string.

eg: say for string2
it would count from

Code:
>String2
qwwerrtyuiopasdfghjmnbvfklzxerbvcwghjjkoowwqerrtggbddqsdfgaqwcxzakjtyugfsdefrtgyhujiknbbbbcdcdcxsxsx zxzxcvcfcdcg
>String3

till the start of string3? ( ie. till '>' of string 3)

I hope I am not confusing.

Please use code tags for posting code fragments or data samples.

I would suggest you to post expected output as well to avoid any confusion.

Try (untested)
Code:
awk '{print length ($0)}' RS=">" ORS=">" file
