Hi,
I had two data file (File1, File2), each one just have one column, but two file were very big. File2 is smaller, all its data included in File1. I want to ouput the result which don't have any data in File2. Could any one give me a help on how to do that?
Thanks in advance!

Please help me, I have two files. I need to output the difference of contents of each file in another file. For example, I need to know the content of the file1 that does not exist on file2 and vice versa. Please take note that the size of the files are large. How can I do it using unix... (4 Replies)
I have an archive file that holds a batch of statements. I would like to be able to extract a certain statement based on the unique customer # (ie. 123456). The end for each statement is noted by "ENDSTM".
I can find the line number for the beginning of the statement section with sed.

Hi Everyone,
I have two files i.e. one file2 contains today's data and the other file1 contains Yesterday's data.
The data in the files contains 226 columns and the data for the coulums separated by a Pipe "|" delimiter.
Now, I have 4 Primary keys (coulumns) by which I have to compare file2 and... (10 Replies)
Hallo Everyone.
I have to admit I'm shell scripting illiterate . I need to find certain strings in several text files and replace each of the string by unique & corresponding text.
I prepared a csv file with 3 columns: <filename>;<old_pattern>;<new_pattern>

Good morning all,
I have a problem that is one step beyond a standard awk compare.
I would like to compare three files which have several thousand records against a fourth file. All of them have a value in each row that is identical, and one value in each of those rows which may be duplicated... (1 Reply)

Hi all,
i have a binary file splitted into 2 chunks, first part with all high bytes and the second part with all low bytes.
I need to combine the two chunks into one binary file like (eg. exactly the reverse of the splitting method solved in the thread # 130940)

comb
comb(1) General Commands Manual comb(1)NAME
comb - Combines Source Code Control System (SCCS) deltas
SYNOPSIS
comb [-clist] [-os] [-pSID] file...
The comb command writes to standard output a shell procedure for combining the specified deltas (SIDs) of an SCCS file and creating a new
version of the file with fewer deltas.
OPTIONS
Each option or group of options applies independently to each named file. Specifies a list of deltas (SIDs) that the shell procedure will
preserve (see get -ilist). The procedure will combine all other deltas. Accesses the reconstructed file at the release of the delta to be
created for each get -e generated; otherwise, accesses the reconstructed file at the most recent ancestor. Using the -o option may
decrease the size of the reconstructed SCCS file. It may also alter the shape of the delta tree of the original file. Specifies the SID
of the oldest delta for the resulting procedure to preserve. All older deltas are combined in the reconstructed file. Causes comb to gen-
erate a shell procedure that, instead of combining the deltas, produces a report for each file, which lists the file name, size (in blocks)
after combining, original size (also in blocks), and percentage change computed by the following formula: 100 * (original - combined) /
original
Run comb using this option before actually combining SCCS deltas in order to judge how much space will actually be saved by the com-
bining process.
DESCRIPTION
By piping the output of the comb command to a shell, or redirecting the output to a file and running that file as a shell procedure, you
can reduce the size of your SCCS file. You can first see how much the file will be reduced by running the comb command with the -s option.
If you specify a directory in place of file, the comb command performs the requested actions on all SCCS files (that is, those with file
names with the s. prefix). If you specify a - (dash) in place of file, the comb command reads standard input and interprets each line as
the name of an SCCS file. The comb command continues to take input until it reads End-of-File.
If you do not specify any options, the comb command preserves only leaf deltas and the minimal number of ancestors needed to preserve the
tree (see the delta command).
The comb command may rearrange the shape of the tree deltas.
The comb command may not save any space; in fact, it is possible for the reconstructed file to actually be larger than the original.
EXAMPLES
To generate a report on how much space will be saved by combing all deltas older than SID 1.4 for SCCS file s.test.c, enter: comb -p1.4 -s
s.test.c | sh To actually combine the deltas, enter: comb -p1.4 s.test.c | sh
