Hi all,
Pls. let me know whether there is any concept called "FILE SETS" in unix?
Because, I am using ETL tool DataStage which creates FILE SETS.
While I am able to view the data of such a file set in the tool, the "cat" command on this FILESET lists only the Metadata and not the data content... (2 Replies)

Hi, this is about sorting a very large file (like 10 gb) to keep lines with unique entries across SOME of the columns.
The line originally looked like this:
sort -u -k2,2 -k3,3n -k4,4n -k5,5n -k6,6n file_unsorted > file_sorted
please note the -u flag.
The problem is that this single... (4 Replies)
I have 84 files with the following names splitseqs.1, spliseqs.2 etc.
and I want to change the .number to a unique filename.
E.g.
change splitseqs.1 into splitseqs.7114_1#24
and
change spliseqs.2 into splitseqs.7067_2#4
So all the current file names are unique, so are the new file names.... (1 Reply)
Hello,
I have a database of name variants with the following structure:
variant=variant=variant
The number of variants can be as many as thirty to forty.
Since the database is quite large (at present around 60,000 lines) duplicate sets of variants creep in. Thus

split
SPLIT(1) BSD General Commands Manual SPLIT(1)NAME
split -- split a file into pieces
SYNOPSIS
split -d [-l line_count] [-a suffix_length] [file [prefix]]
split -d -b byte_count[K|k|M|m|G|g] [-a suffix_length] [file [prefix]]
split -d -n chunk_count [-a suffix_length] [file [prefix]]
split -d -p pattern [-a suffix_length] [file [prefix]]
DESCRIPTION
The split utility reads the given file and breaks it up into files of 1000 lines each (if no options are specified), leaving the file
unchanged. If file is a single dash ('-') or absent, split reads from the standard input.
The options are as follows:
-a suffix_length
Use suffix_length letters to form the suffix of the file name.
-b byte_count[K|k|M|m|G|g]
Create split files byte_count bytes in length. If k or K is appended to the number, the file is split into byte_count kilobyte
pieces. If m or M is appended to the number, the file is split into byte_count megabyte pieces. If g or G is appended to the num-
ber, the file is split into byte_count gigabyte pieces.
-d Use a numeric suffix instead of a alphabetic suffix.
-l line_count
Create split files line_count lines in length.
-n chunk_count
Split file into chunk_count smaller files.
-p pattern
The file is split whenever an input line matches pattern, which is interpreted as an extended regular expression. The matching line
will be the first line of the next output file. This option is incompatible with the -b and -l options.
If additional arguments are specified, the first is used as the name of the input file which is to be split. If a second additional argument
is specified, it is used as a prefix for the names of the files into which the file is split. In this case, each file into which the file is
split is named by the prefix followed by a lexically ordered suffix using suffix_length characters in the range ``a-z''. If -a is not speci-
fied, two letters are used as the suffix.
If the prefix argument is not specified, the file is split into lexically ordered files named with the prefix ``x'' and with suffixes as
above.
ENVIRONMENT
The LANG, LC_ALL, LC_CTYPE and LC_COLLATE environment variables affect the execution of split as described in environ(7).
EXIT STATUS
The split utility exits 0 on success, and >0 if an error occurs.
SEE ALSO csplit(1), re_format(7)STANDARDS
The split utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
A split command appeared in Version 3 AT&T UNIX.
BUGS
The maximum line length for matching patterns is 65536.
