I was thinking is to extract a certain amount of lines after a pattern from Name.txt has matched in sequence.faa. The problem is I'm not sure whether awk, sed or grep can accomplish such output. Can anyone give me some solutions or directions to tackle this issue? Ps: The above files are examples, not the actual file that Im been working on.
Solution
I would harness GNU AWK for this task following way, let names.txt content be
XP_037759835.2
XP_037759838.2
XP_037759836.2
and file.txt content be
>NP_001277599.1 actin, alpha cardiac muscle 1 [Chelonia mydas]

Explanation: when processing 1st file (FNR==NR) I built regex by joining newline separated fields using pipe (|) which means alternative (OR) and instruct GNU AWK to go to next line so nothing other happens when processing files, when processing following files I print line if it does match regex and I prepend it > as it was consumed due to being row separator (RS). Dislcaimer: this solution assumes that there are not spaces in first file and characters of special meaning in regular expression are not problem (e.g. here . are treated as any character).
(tested in GNU Awk 5.0.1)
