... and another one Smilie

Code:
awk 'NR==FNR{p=$0;next}
{r=FS=$0;$0=p;printf "%s=%d\n",r,NF-1}' file1 file2

Use nawk or /usr/xpg4/bin/awk on Solaris.

Example:
Code:
% cat file1              
ACFCFACCACARCSHFARCVJVASTVAJFTVAJVGHBAJ
% cat file2              
A
C
F
R
% awk 'NR==FNR{p=$0;next}
{r=FS=$0;$0=p;printf "%s=%d\n",r,NF-1}' file1 file2
A=9
C=7
F=4
R=2

Hi.

A brief improvisation on radoulov's inventive zsh script -- move the read outside the loop -- probably a negligible difference for short files, however, could make a difference for longer files (a manifestation of my habit of moving invariant code outside Fortran loops Smilie ):
Code:
#!/bin/zsh

# @(#) s2       Demonstrate small optimization, avoid repeated reads.

FILE=${1-data1}

echo
echo " Input $FILE:"
cat $FILE

# <data2 while read;do printf "%s=%d\n" "$REPLY" "${#$(<data1)//[^$REPLY]}";done

echo
echo " Results:"
t1=$(<$FILE)
while read
do
  printf "%s=%d\n" "$REPLY" "${#${t1//[^$REPLY]}}"
done <data2

exit 0

Producing:
Code:
% ./s2

 Input data1:
ACFCFACCACARCSHFARCVJVASTVAJFTVAJVGHBAJ

 Results:
A=9
C=7
F=4
R=2

cheers, drl

awk

Hi,
Hope this one can help you.

Code:
sed '/^$/d' b > tb
sed '/^$/d' a > ta
awk '{
if (length($1)>3)
for (i=1;i<=length($1);i++)
arr[substr($1,i,1)]++
else
print $1" = "arr[$1]
}
' tb ta
