Filter file by length, looking only at lines that don't begin with ">"
I have a file that stores data in pairs of lines, following this format:
line 1: header (preceded by ">")
line 2: sequence
Example.txt:
I want to filter out the sequences and corresponding headers for all sequences that are less than 11 characters. Desired output:
I can search each line for lines less than 11 characters, and print that line along with the header. The problem I'm having is ignoring the headers (i.e. lines beginning with ">") when I do the length search.
For example
Gives me
How do I tell awk not to ignore lines beginning with ">"?
