Matching two file contents and extracting associated information
Hi, I am new to shell programming and need help. I have File1 with some ID numbers and File2 with ID number and some associated information.
I want to match the ID numbers from File1 to contents in File2 and output a third file which pulls out the ID numbers and the associated information with the match.
For example
cat File1 cat File2 I want to match the ID numbers from File1 with File2 and output not only the lines that match but also get the associated information which ends before “>sequence”.
The needed output is :
It will be very helpful if you can suggest how to do this. Thanks

fnmatch
FNMATCH(3) 1 FNMATCH(3)fnmatch - Match filename against a patternSYNOPSIS
bool fnmatch (string $pattern, string $string, [int $flags])
DESCRIPTION fnmatch(3) checks if the passed $string would match the given shell wildcard $pattern.
PARAMETERS
o $pattern
- The shell wildcard pattern.
o $string
- The tested string. This function is especially useful for filenames, but may also be used on regular strings. The average user
may be used to shell patterns or at least in their simplest form to '?' and '*' wildcards so using fnmatch(3) instead of
preg_match(3) for frontend search expression input may be way more convenient for non-programming users.
o $flags
- The value of $flags can be any combination of the following flags, joined with the binary OR (|) operator.

|FNM_CASEFOLD | |
