Hi.

Here is an example:
Code:
#!/usr/bin/env sh

# @(#) s1       Demonstrate counting specific characters.

set -o nounset
echo

## Use local command version for the commands in this demonstration.

version bash tr wc head

# Create data file, from which line 1 will be examined.

cat >data1 <<'EOF'
aaa|bbb|ccc|||
ddd||eee|fff||
EOF

echo
echo " Counting \"|\", expecting 5:"
head -1 data1 |
tr -dc '|' |
wc -c

exit 0

Producing:
Code:
% ./s1

GNU bash, version 2.05b.0(1)-release (i386-pc-linux-gnu)
tr (coreutils) 5.2.1
wc (coreutils) 5.2.1
head (coreutils) 5.2.1

 Counting "|", expecting 5:
5

Modify as you need to, see man pages for details ... cheers, drl
