I want to count the number of occurrences of numbers from a file of 6,000,000 lines. Because its too large, I decided to split the counts up in multiple files. So I have files of the counts of 5,000 lines. Now I want to add up the counts of all those files.
The "counts file" looks like this:
So I have multiple of those "counts files" which I want to sum.
Does somebody have an idea?
Thanks!

I have a command which returns some numbers as follows:
$ls -l ${dbname}.ix* | awk '{print $5 }'
929792
36864
57344
73728
53248
114688
How can I find the sum of those numbers by piping this output into 'awk' or some other editor/command? Thanks a lot -A (3 Replies)
I have 11 directories with around 200 files in each. In each directory the files are labeled out.0 through out.201 . Each file has around 118 numbers in a single column. I need to sum the files in each directory so each directory will have a resultant vector that is 118 numbers long. I then... (5 Replies)

csplit
csplit(1) General Commands Manual csplit(1)Name
csplit - context split
Syntax
csplit [ -s ] [ -k ] [ -f prefix ] file arg1 [ ...argn ]
Description
The command reads file and separates it into n+1 sections, as defined by the arguments arg1...argn. By default, the sections are placed in
xx00...xxn (n may not be greater than 99). The named file is sectioned in the following way:
00: From the start of file up to (but not including) the line referenced by arg1.
01: From the line referenced by arg1 up to the line referenced by arg2.
.
.
.
n: From the line referenced by argn to the end of file.
If the file argument is a minus (-) then standard input is used. A minus is an ASCII octal 055.
Options-s Suppresses the printing of all character counts. If the -s option is omitted, the command prints the character counts
for each file created.
-k Leaves previously created files intact. If the -k option is omitted, automatically removes created files if an error
occurs.
-fprefix Names the created files prefix00...prefixn. The default is xx00...xxn.
The arguments (arg1...argn) to can be a combination of the following:
/rexp/[offset] A file is created for the section from the current line up to (but not including) the line containing the regular
expression rexp. The current line becomes the line containing rexp. The optional offset is plus (+) or minus
(-) the number of lines. For example, /Page/-5.
%rexp%[offset] This argument is the same as /rexp/[offset], except that no file is created for the section.
lnno A file is created from the current line up to (but not including) lnno. The current line becomes lnno.
{num} Repeat argument. This argument may follow any of the above arguments. If it follows a rexp argument, that argu-
ment is applied num more times. If it follows lnno, the file will be split every lnno lines (num times) from
that point.
Enclose all rexp type arguments that contain blanks or other characters meaningful to the Shell in the appropriate quotes. Regular expres-
sions should not contain embedded new-lines. The command does not affect the original file; it is the user's responsibility to remove it.
Examples
csplit -f cobol file /procedure division/ /par5./ /par16./
This example creates four files, cobol00...cobol03. After editing the files that created, they can be recombined as follows:
cat cobol0[0-3] > file
Note that this example overwrites the original file.
csplit -k file 100 {99}
This example splits the file every 100 lines, up to 10,000 lines. The -k option causes the created files to be retained if there are less
than 10,000 lines; however, an error message would still be printed.
csplit -k prog.c '%main(%' '/^}/+1' {20}
Assuming that follows the normal C coding convention of ending routines with a right brace (}) at the beginning of the line, this example
creates a file containing each separate C routine (up to 21) in
Diagnostics
The diagnostics are self explanatory except for the following:
arg - out of range
This message means that the given argument did not reference a line between the current position and the end of the file.
