Top Forums Shell Programming and Scripting awk for splitting file in constant chunks Post 302659065 by Corona688 on Wednesday 20th of June 2012 10:29:19 AM

Remember that the entire outer code block runs once per line. 'print' doesn't cause it to read another line, even if you didn't have syntax errors your code would just be printing the same line over and over.

Also, $ doesn't mean "variable", $ means "column". If you just want the value of the variable you don't need $.

How the above program works is

Code:
# If NR is a multiple of 2500, increment i.
!(NR%2500){i++;}
# Print into fi.
{print > "f"i;}

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
