I need to find a string of 13 character length in a text file that has a duplicate close to it.
It referencing to the mutation 13 of the genomes.
For example:
ACGAATTGCAGCCACAGTACGAATCGCAGCC.
It starts with ACGAATTGCAGCC and ends with it, but in between are random chars of unknown length.
What I've come up so far is:
grep -Eo '((.)13).1,1001'
I have to find it in this

You were quite close, the problem was the 100, too narrow! You may want to consider using Perl PCRE as opposed to Posix Extended. The performance difference is quite noticeable.

You may want to make the repetition non greedy.1,1000?, even if this may not matter in this exact case, you only want to include up to the nearest repetition. That horrible slowness with-Elooks like a bug (LC_ALL=Cwill cut it to 1/3, but still orders of magnitude slower than-P).

P.S.: @mosvy - nice catch w/ the LC_ALL ... that brings the runtime down to0m0.714s... almost sevenfold faster. Still a good tick slower than-P. :)

Note that POSIX EREs don't have back references. (POSIX BREs do). The OP is probably using an implementation that offers it as an extension.
