Top Forums Shell Programming and Scripting Need HELP with AWK split. Need to check for "special characters" in string before splitting the file Post 302678997 by shell_boy23 on Monday 30th of July 2012 06:14:03 AM

I tuned the regex as suggested. But it does not give the required output.
code used:
Code:
awk -F, '{if ($NF ~ /[0-9]$|[A-Za-z]$/) print >"goodfile"; else print >"badfile"}' samp.txt

samp.txt
Code:
1,abc,def,1234,A *
2,bed,dec,342,* A
3,dec,345,23,*&^
4,sdf,fgh,234,
5,ert,345,ghj,C*2
6,ert,345,sdf,123

Output
Code:
$ cat goodfile
2,bed,dec,342,* A
5,ert,345,ghj,C*2
6,ert,345,sdf,123
$ cat badfile
1,abc,def,1234,A *
3,dec,345,23,*&^
4,sdf,fgh,234,

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
