Hello,
I figured out what to do in order to make my program do what I want it to do:

vi (gets you to the VIM program)

e: filename.txt (opens up the text file you want to manipulate)

:%g!/searchwords/d (looks for the words you are searching for in your document, and deletes any row that doesn't contain this information)

:w newfilename.txt (saves the information left over (the info you are looking for) as a new text file)


So, let's say this is my newfilename.txt document:

Code:
1234    someinfo1    moreinfo1, 1235
1236    someinfo2    moreinfo2, 1238
1239    someinfo3    moreinfo3, 5793

and I have some other text file called othertextfile.txt that looks like this:

Code:
1235    someinfo4    moreinfo4
1238    someinfo5    moreinfo5
5793    someinfo6    moreinfo6

and I want my program to go through newfilename.txt and look at all the numbers found in the third column of the first file (1235, 1238, 5793) and output the corresponding 3rd column in the second file, for each one

i.e.
the third column of the first file has the numbers 1235, so it would find 1235 in the second file and output 1235 moreinfo4.


I'd like to continue using vi if possible


Thank you

elf_getphdr(3E) 														   elf_getphdr(3E)

NAME
elf32_getphdr, elf32_newphdr, elf64_getphdr, elf64_newphdr - retrieve class-dependent program header table for elf32 and elf64 files, respectively SYNOPSIS
[flag... ] file... [library] ... DESCRIPTION
For a 32-bit class file, returns a pointer to the program execution header table, if one is available for the ELF descriptor elf. allocates a new table with count entries, regardless of whether one existed previously, and sets the bit for the table (see elf_flag(3E)). Specifying a zero count deletes an existing table. Note this behavior differs from that of (see elf_getehdr(3E)), allowing a program to replace or delete the program header table, changing its size if necessary. If no program header table exists, the file is not a 32-bit class file, an error occurs, or elf is null, both functions return a null pointer. Additionally, returns a null pointer if count is zero. The table is an array of structures, each of which includes the following members. The ELF header's member tells how many entries the program header table has (see elf_getehdr(3E)). A program may inspect this value to determine the size of an existing table; automatically sets the member's value to count. If the program is building a new file, it is responsible for creating the file's ELF header before creating the program header table. For a 64-bit class file, returns a pointer to the program execution header table, if one is available for the ELF descriptor elf. allocates a new table with count entries, regardless of whether one existed previously, and sets the bit for the table (see Specifying a zero count deletes an existing table. Note this behavior differs from that of (see elf_getehdr(3E)), allowing a program to replace or delete the program header table, changing its size if necessary. If no program header table exists, the file is not a 64-bit class file, an error occurs, or elf is null, both functions return a null pointer. Additionally, returns a null pointer if count is zero. The table is an array of structures, each of which includes the following members. The ELF header's e_phnum member tells how many entries the program header table has (see elf_getehdr(3E)). A program may inspect this value to determine the size of an existing table; automatically sets the member's value to count. If the program is building a new file, it is responsible for creating the file's ELF header before creating the program header table. SEE ALSO
