Trying to find number of uppercase and lowercase letters.

[kaspareov]

Hello Guys,

I am writing a script which check each line for how many Uppercase and Lowercase letter of a given file. Please check my script as follow:

l=0

while read line
do
echo Line `expr $l + 1` has ` tr -cd "[A-Z]" < $line | wc -c` uppercase letters and
 `tr -cd "[a-z]" < $line | wc -c` lowercase letters.

l=`expr $l + 1`
done < $1

I am not getting what is wrong. I am not getting answer. Is anyone can help me?

Best Regards,

How about using grep instead of tr?

#!/bin/bash
[ $# -ne 1 ] && echo Give me a file && exit 1
file=$1

i=1
while read line; do
  printf "\nLine $i: \"$line\"\n"
  printf "Lower case: "
  echo $line|/bin/grep -o [a-z]|wc -l
  printf "Upper case: "
  echo $line|/bin/grep -o [A-Z]|wc -l
  i=$(( $i + 1 ))
done < $file

Thanks atreyu, but your code showing No match found. My folllowing code is working partially. It is skiping some lines and also giving either Lowercase or Uppercase.

l=0

while read line
do

   lo=`line | tr -cd "[a-z]" | wc -c`
echo $lo
echo Line `expr $l + 1` has `line | tr -cd "[A-Z]" | wc -c` uppercase letters an
d `line | tr -cd "[a-z]" | wc -c` lowercase letters.

l=`expr $l + 1`
done < $1

Can you help me to short out this problem?

Thanking You,

My code works for me...

[user@host ~]$
[user@host ~]$ cat test.sh
#!/bin/bash
[ $# -ne 1 ] && echo Give me a file && exit 1
file=$1

i=1
while read line; do
  printf "\nLine $i: \"$line\"\n"
  printf "Lower case: "
  echo $line|/bin/grep -o [a-z]|wc -l
  printf "Upper case: "
  echo $line|/bin/grep -o [A-Z]|wc -l
  i=$(( $i + 1 ))
done < $file
[user@host ~]$
[user@host ~]$ cat blah.txt
AAAAAAAAAAAAAa
bb
ccCC
dddDDD

asdfaslkdsdfas
[user@host ~]$
[user@host ~]$ sh test.sh blah.txt

Line 1: "AAAAAAAAAAAAAa"
Lower case: 1
Upper case: 13

Line 2: "bb"
Lower case: 2
Upper case: 0

Line 3: "ccCC"
Lower case: 2
Upper case: 2

Line 4: "dddDDD"
Lower case: 3
Upper case: 3

Line 5: ""

Line 6: "asdfaslkdsdfas"

[user@host ~]$

Perhaps show your text file and how you are calling it.
