I'm afraid sed (alone) can't do that, as it can't calculate nor count. On top, your request is not quite clear - does the term "char" as used by you include digits and punctuation etc, or not? Please specify. If all that is included, try a combination like
Code:
sed ':L; $ {s/\n//g;
            s/<\/test1>/\n/g
            s/<test>\|<tag.>.*<\/tag.>//g
            s/\n$//}
      N; bL
' file |
{ while read LN
     do [ ${#LN} -ge 30 ] && A=$((A+1)) || U=$((U+1))
     done
     echo "0 - 30 char: " $U
     echo "  > 30 char: " $A
}
0 - 30 char:  2
  > 30 char:  1

NAME
cut - select out columns of a file SYNOPSIS
cut [ -b | -c] list [file...] cut -f list [-d delim] [ -s] OPTIONS
-b Cut specified bytes -c Select out specific characters -d Change the column delimiter to delim -f Select out specific fields that are separated by the -i Runs of delimiters count as one -s Suppres lines with no delimiter characters, when used EXAMPLES
cut -f 2 file # Extract field 2 cut -c 1-2,5 file # Extract character columns 1, 2, and 5 cut -c 1-5,7- file # Extract all columns except 6 DESCRIPTION
[file...]" delimiter character ( see delim)" with the -f option. Lines with no delimiters are passwd through untouched" Cut extracts one or more fields or columns from a file and writes them on standard output. If the -f flag is used, the fields are sepa- rated by a delimiter character, normally a tab, but can be changed using the -d flag. If the -c flag is used, specific columns can be specified. The list can be comma or BLANK separated. The -f and -c flags are mutually exclusive. Note: The POSIX1003.2 standard requires the option -b to cut out specific bytes in a file. It is intended for systems with multi byte characters (e.g. kanji), since MINIX uses only one byte characters, this option is equivalent to -c. For the same reason, the option -n has no effect and is not listed in this man- ual page. SEE ALSO
