I'm not sure what thes files look like. But if they are sorted on the id field it sounds like this is just what the "join" command does. Here is a sample run:
I am trying to cat a file and then grep that file for a number. I can do it fine on other files but this particular file will not do anything. I tried running it on an older file from the same device but it is just not working. The file is nothing more than a flat file on a unix box. Here is just a... (3 Replies)

I am not sure if using cat -n is the most efficient way to split a file into multiple files, one file per line in the source file.
I thought using cat -n would make it easy to process the file because it produces an output that numbers each line that I could then grep for with the regex "^ *$i".... (3 Replies)

mv
MV(1) General Commands Manual MV(1)NAME
mv - move or rename files
SYNOPSIS
mv [ -i ] [ -f ] [ - ] file1 file2
mv [ -i ] [ -f ] [ - ] file ... directory
DESCRIPTION
Mv moves (changes the name of) file1 to file2.
If file2 already exists, it is removed before file1 is moved. If file2 has a mode which forbids writing, mv prints the mode (see chmod(2))
and reads the standard input to obtain a line; if the line begins with y, the move takes place; if not, mv exits.
In the second form, one or more files (plain files or directories) are moved to the directory with their original file-names.
Mv refuses to move a file onto itself.
Options:
-i stands for interactive mode. Whenever a move is to supercede an existing file, the user is prompted by the name of the file followed
by a question mark. If he answers with a line starting with 'y', the move continues. Any other reply prevents the move from occur-
ring.
-f stands for force. This option overrides any mode restrictions or the -i switch.
- means interpret all the following arguments to mv as file names. This allows file names starting with minus.
SEE ALSO cp(1), ln(1)BUGS
If file1 and file2 lie on different file systems, mv must copy the file and delete the original. In this case the owner name becomes that
of the copying process and any linking relationship with other files is lost.
