[Solved] Awk: count occurrence of each character for every field
Hi,

let's say an input looks like:
Code:
A|C|C|D
A|C|I|E
A|B|I|C
A|T|I|B

as the title of the thread explains, I am trying to get something like:
Code:
1|A=4
2|C=2|B=1|T=1
3|I=3|C=1
4|D=1|E=1|C=1|B=1

i.e. a count of every character in each field (first column of output) independently, sorted horizontally from the largest to smallest (like in output record 2 and 3 for instance).

I posted a similar question months ago (count number of distinct values in each column with awk | Unix Linux Forums | UNIX for Dummies Questions & Answers), and tried to adapt it as follow:
Code:
awk ' BEGIN {FS="|"}{for(i=1; i<=NF; i++){group[$i]++}} END{for(c in group) {print c " = " group[c]}}'

but it counts the character for the entire file and not independently for each field.

Any help would be greatly appreciated !

Thanks in advance !

colrm

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME

     colrm -- remove columns from a file

SYNOPSIS

     colrm [start [stop]]

DESCRIPTION

     The colrm utility removes selected columns from the lines of a file.  A column is defined as a single character in a line.  Input is read
     from the standard input.  Output is written to the standard output.

     If only the start column is specified, columns numbered less than the start column will be written.  If both start and stop columns are spec-
     ified, columns numbered less than the start column or greater than the stop column will be written.  Column numbering starts with one, not
     zero.

     Tab characters increment the column count to the next multiple of eight.  Backspace characters decrement the column count by one.

ENVIRONMENT

     The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).

EXIT STATUS

     The colrm utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     awk(1), column(1), cut(1), paste(1)

HISTORY

     The colrm command appeared in 3.0BSD.
