Hi there,
I have a couple of files I need to merge. I can do a simple merge by concatenating them into one larger file.
But then I need to filter the file to get a desired result.
The output looks like this:
TRNH 0000000010941
ORDH

I have about 20 CSV's that all look like this:
"","","","","","","","","","","","","","","",""What I've been told I need to produce is the exact same thing, but with each file now containing the start_code from every other file where the email matches.

I have one base file, and multiple target files-- each have uniform line structure so no need to use grep to find things-- can just define sections by line number.
My question is quite simple-- can I use sed to copy a defined block of lines (say lines 5-10) from filename1.txt to overwrite an... (3 Replies)
I have a diff command that does what I want but when comparing large text/log files, it uses up all the memory I have (sometimes over 8gig of memory)
diff file1.txt file2.txt | grep '^<'| awk '{$1="";print $0}' | sed 's/^ *//'
Is there a better more efficient way to find the lines in one file... (5 Replies)

combine
COMBINE(1)COMBINE(1)NAME
combine - combine sets of lines from two files using boolean operations
SYNOPSIS
combine file1 and file2
combine file1 not file2
combine file1 or file2
combine file1 xor file2
_ file1 and file2 _
_ file1 not file2 _
_ file1 or file2 _
_ file1 xor file2 _
DESCRIPTION
combine combines the lines in two files. Depending on the boolean operation specified, the contents will be combined in different ways:
and Outputs lines that are in file1 if they are also present in file2.
not Outputs lines that are in file1 but not in file2.
or Outputs lines that are in file1 or file2.
xor Outputs lines that are in either file1 or file2, but not in both files.
"-" can be specified for either file to read stdin for that file.
The input files need not be sorted, and the lines are output in the order they occur in file1 (followed by the order they occur in file2
for the two "or" operations). Bear in mind that this means that the operations are not commutative; "a and b" will not necessarily be the
same as "b and a". To obtain commutative behavior sort and uniq the result.
Note that this program can be installed as "_" to allow for the syntactic sugar shown in the latter half of the synopsis (similar to the
test/[ command). It is not currently installed as "_" by default, but you can alias it to that if you like.
