I've been searching around here and other places, but can't put this together...
I've got a unique list of words in file 1 (one word on each line).
I need to delete each line in file2 that begins with the word in file1.
I started this way, but want to know how to use file1 words instead... (13 Replies)

Hi All,
as you can see I'm pretty new to this board. :D
I'm struggling around with small script to search a few fields in another file.
Basically I have file1 looking like this:

I have very limited coding skills but I'm wondering if someone could help me with this. There are many threads about matching strings in two files, but I have no idea how to add a column from one file to another based on a matching string.
I'm looking to match column1 in file1 to the number... (3 Replies)

I need to find matches for any lines in file1 that appear in file2. Desired output is '>' plus the file1 term, followed by the line after the match in file2 (so the title is a little misleading):
This is honestly beyond what I can do without spending the whole night on it, so I'm... (2 Replies)
I have 2 files with 7 fields and i want to print the lines which is present in file1 but not in file2 based on field1 and field2.
Logic: I want to print all the lines, where there is a particular column1 and column2. And we do not find the set of column1 and column2 in file2.
Example: "sc2/10... (3 Replies)
I have two files.
File 1 is a two-column index file, e.g.
comp11084_c0_seq6:130-468(-) comp12746_c0_seq3:140-478(+)
comp11084_c0_seq3:201-539(-) comp12746_c0_seq2:191-529(+)
File 2 is a sequence file with headers named with the same terms that populate file 1. ... (1 Reply)
Hi,
I am running my pipeline and capturing all stout from multiple programs to a .txt file. I want to go into that .txt file and search for specific lines, and finally print those lines in a second .txt file.
I can do this using grep, awk, or sed for each line, but have not been able to get... (2 Replies)
I want to print only the lines in file2 that match file1, in the same order as they appear in file 1
file1

desired output:
I'm getting the lines to match

but they are in sorted order, which is not what I want:
Can anyone... (4 Replies)

getdelim
GETDELIM(3) BSD Library Functions Manual GETDELIM(3)NAME
getdelim, getline -- read a delimited record from a stream
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
ssize_t
getdelim(char ** restrict lineptr, size_t * restrict n, int delimiter, FILE * restrict stream);
ssize_t
getline(char ** restrict lineptr, size_t * restrict n, FILE * restrict stream);
DESCRIPTION
The getdelim() function reads from the stream until it encounters a character matching delimiter, storing the input in *lineptr. The buffer
is NUL-terminated and includes the delimiter. The delimiter character must be representable as an unsigned char.
If *n is non-zero, then *lineptr must be pre-allocated to at least *n bytes. The buffer should be allocated dynamically; it must be possible
to free(3) *lineptr. getdelim() ensures that *lineptr is large enough to hold the input, updating *n to reflect the new size.
The getline() function is equivalent to getdelim() with delimiter set to the newline character.
RETURN VALUES
The getdelim() and getline() functions return the number of characters read, including the delimiter. If no characters were read and the
stream is at end-of-file, the functions return -1. If an error occurs, the functions return -1 and the global variable errno is set to indi-
cate the error.
The functions do not distinguish between end-of-file and error, and callers must use feof(3) and ferror(3) to determine which occurred.
EXAMPLES
The following code fragment reads lines from a file and writes them to standard output.
char *line = NULL;
size_t linesize = 0;
ssize_t linelen;
while ((linelen = getline(&line, &linesize, fp)) != -1)
fwrite(line, linelen, 1, stdout);
if (ferror(fp))
perror("getline");
ERRORS
[EINVAL] lineptr or n is a NULL pointer.
[EOVERFLOW] More than SSIZE_MAX characters were read without encountering the delimiter.
The getdelim() and getline() functions may also fail and set errno for any of the errors specified in the routines fflush(3), malloc(3),
read(2), stat(2), or realloc(3).
SEE ALSO ferror(3), fgets(3), fopen(3)STANDARDS
The getdelim() and getline() functions conform to IEEE Std 1003.1-2008 (``POSIX.1'').
