Hi ,
I have a peculiar case, where my sed command is working on a file which contains lines of small length.
sed "s/XYZ:1/XYZ:3/g" abc.txt > xyz.txt
when abc.txt contains lines of small length(currently around 80 chars) , this sed command is working fine.

Hi experts.
I got a file (500mb max) and need to pivot it (loading into ORCL) and change BLANK delimiter to PIPE |.
Sometimes there are multipel BLANKS (as a particular value may be BLANK, or simply two BLANKS instead of one BLANK).
thanks for your input!
Cheers,

Hi all,
I am using Sed to convert a log file into a csv, so far so good. Kudos to this forum for helping me thus far!
My current problem. There are some lines in the log file that I do not want. How can I delete lines where the line legth is less than say 100?
Here are some sample lines... (6 Replies)
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)
Hi everyone,
I have two files (A and B) and want to combine them to one by always taking 10 rows from file A and subsequently 6 lines from file B. This process shall be repeated 40 times (file A = 400 lines; file B = 240 lines).
Does anybody have an idea how to do that using perl, awk or sed?... (6 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)
Hello,
I have a file with a date field with various lengths. For example:
m/d/yyyy hh:mm or h:mm
mm/dd/yyyy hh:mm or h:mm
Is there a way using sed or awk to change the field to m/d/y ? I don't need the hours and minutes in that field, just the date in the proper format.
Thanks in... (6 Replies)

join
JOIN(1) General Commands Manual JOIN(1)NAME
join - relational database operator
SYNOPSIS
join [-an] [-e s] [-o list] [-tc] file1 file2
DESCRIPTION
Join forms, on the standard output, a join of the two relations specified by the lines of file1 and file2. If file1 is `-', the standard
input is used.
File1 and file2 must be sorted in increasing ASCII collating sequence on the fields on which they are to be joined, normally the first in
each line.
There is one line in the output for each pair of lines in file1 and file2 that have identical join fields. The output line normally con-
sists of the common field, then the rest of the line from file1, then the rest of the line from file2.
Fields are normally separated by blank, tab or newline. In this case, multiple separators count as one, and leading separators are dis-
carded.
These options are recognized:
-an In addition to the normal output, produce a line for each unpairable line in file n, where n is 1 or 2.
-e s Replace empty output fields by string s.
-o list
Each output line comprises the fields specified in list, each element of which has the form n.m, where n is a file number and m is a
field number.
-tc Use character c as a separator (tab character). Every appearance of c in a line is significant.
SEE ALSO sort(1), comm(1), awk(1).
BUGS
With default field separation, the collating sequence is that of sort -b; with -t, the sequence is that of a plain sort.
The conventions of join, sort, comm, uniq, look and awk(1) are wildly incongruous.
