Count lowercase in a word

dcfargo · #1 (**permalink**) 06-25-2008

I have a file like:

aabbccddDDCCDDCCaabbcc 123
CCaaCCBBCCaaaaaaaCCCaa 234
CCDDCCAACCCCccccccccaa 999

I'd like to print out the 1st word followed by the number of lowercase characters in that word. The words only consist of a few letters.

I was trying something like

awk '{a+=gsub(a,a) b+=gsub(b,b) c+=gusb(c,c) d+=(gsub(
d,d) x=(a+b+c+d) END {print $1, X}' infile >outfile

Thanks so much for your help.

Code:

echo 'aabbccddDDCCDDCCaabbcc' | awk '{print $0, gsub("[a-z]", ".")}'

I'm using Bash and going with:

awk '{print $1, gsub("[a-z]", ".")}' infile > outfile

appears to be counting all the letters not just the lowercase letters

Thank you

going with [a,b,c,d] worked for some reason so I'll just use that.

Thanks so much.

The following works in ksh93 and should also work in bash.

Code:

#!/usr/bin/ksh93

while read str num
do
   strU=${str//[^A-Z]}
   print "${str} ${#strU}"
done < file

On your sample file, it produces the following output

Code:

aabbccddDDCCDDCCaabbcc 8
CCaaCCBBCCaaaaaaaCCCaa 11
CCDDCCAACCCCccccccccaa 12

Code:

# cat aaa
aabbccddDDCCDDCCaabbcc 123
CCaaCCBBCCaaaaaaaCCCaa 234
CCDDCCAACCCCccccccccaa 999

# for i in `cut -f1 aaa -d ' '`; do echo -n "$i "; echo -n $i | sed 's/[^a-z]//g' | wc -c; done
aabbccddDDCCDDCCaabbcc 14
CCaaCCBBCCaaaaaaaCCCaa 11
CCDDCCAACCCCccccccccaa 10

Hi,

I have a similar problem where i need to count stretches of lower- and upper-case letters within words like

ttgggcTGGCCGCCCCCCAGggc
ttgggcTGGCCGCtgggcttCCCCCAGggc

the output could look like:

ttgggcTGGCCGCCCCCCAGggc lower 5 upper 12 lower 3
ttgggcTGGCCGCtgggcttCCCCCAGggc lower 5 upper 7 lower 6 upper 6 lower 3

any help would be appreciated,

best
robert
