read regex from ID file, print regex and line below from source file
I have a file of protein sequences with headers (my source file). Based on a list of IDs (which are included in some of the headers), I'd like to print out only the specified sequences, with only the ID as header.
In other words, I'd like to search source.txt for the terms in IDs.txt, and print the ID as well as the sequence. Ideally the process would continue even if an ID is not found in the source file. All headers in source.txt are of similar format.
I am able to pull out the sequences based on the ID one-by-one, but this is slow and doesn't give me the header.
I also tried extracting the entire header and the sequence by modifying a script I had for a sequence file with different header type, but again it's one-by-one it only prints the header.
As is probably clear, I'm still pretty low on the learning curve. Any help would be really appreciated!

Hi experts,
I have a file with regexes which is used for automatic searches on several files (40+ GB).
To do some postprocessing with the grep result I need the matching line as well as the match itself.
I know that the latter could be achieved with grep's -o option. But I'm not aware of a... (2 Replies)

ne_response_header_iterate
NE_GET_RESPONSE_HEAD(3) neon API reference NE_GET_RESPONSE_HEAD(3)NAME
ne_get_response_header, ne_response_header_iterate - functions to access response headers
SYNOPSIS
#include <ne_request.h>
const char *ne_get_response_header(ne_request *request, const char *name);
void *ne_response_header_iterate(ne_request *request, void *cursor, const char **name, const char **value);
DESCRIPTION
To retrieve the value of a response header field, the ne_get_response_header function can be used, and is given the name of the header to
return.
To iterate over all the response headers returned, the ne_response_header_iterate function can be used. This function takes a cursor
parameter which should be NULL to retrieve the first header. The function stores the name and value of the next header header in the name
and value parameters, and returns a new cursor pointer which can be passed to ne_response_header_iterate to retrieve the next header.
RETURN VALUE
ne_get_response_header returns a string, or NULL if no header with that name was given. If used during request processing, the return value
pointer is valid only until the next call to ne_begin_request, or else, until the request object is destroyed.
Likewise, the cursor, names, and values returned by ne_response_header_iterate are only valid until the next call to ne_begin_request or
until the request object is destroyed.
EXAMPLES
The following code will output the value of the Last-Modified header for a resource:
ne_request *req = ne_request_create(sess, "GET", "/foo.txt");
if (ne_request_dispatch(req) == NE_OK) {
const char *mtime = ne_get_response_header(req, "Last-Modified");
if (mtime) {
printf("/foo.txt has last-modified value %s
", mtime);
}
}
ne_request_destroy(req);
