I have created one shell script in which it will count number of "~" tilda charactors from each line of the file.But the problem is that i need to count each line count individually, that means. if line one contains 14 "~"s and line two contains 15 "~"s then it should give an error msg.each line having same number of "~"s. so i need to check each line is having same "~" or not . my script gives me output like
**output**
Code:
total = 2
linelength= 62
14
linelength= 62
28
my script
Code:
#!/bin/bash
DATA_DIR=/export/opt/rtrupld/autosys/scripts_old
data=`ls $DATA_DIR/count.txt`
# count1=1
var=`wc -l < $data`
#var2=`expr $var + 1`
echo "total = $var"
#var3=14
tildacount=0
while read line
do
count=0
linelen=`echo "$line"|wc -c`
echo "linelength= $linelen"
if [ $linelen -gt 0 ]
then
# echo $linelen
until [ $count -ge $linelen ]
do
count=`expr $count + 1 `
char=`echo "$line"|cut -b"$count"`
if [ "$char" = "~" ]
then
tildacount=`expr $tildacount + 1`
fi
done
echo $tildacount
fi
done < $data
#echo $tildacount

Hello Experts,
I was wondering how can we get a fall trough case structure.
Eg: If we have two cases A and B and a default; if I do not break after A, it should execute all the statements of A as well as B if I break after B else fall through even lower.

escape
escape(1) Mail Avenger 0.8.3 escape(1)NAME
escape - escape shell special characters in a string
SYNOPSIS
escape string
DESCRIPTION
escape prepends a "" character to all shell special characters in string, making it safe to compose a shell command with the result.
EXAMPLES
The following is a contrived example showing how one can unintentionally end up executing the contents of a string:
$ var='; echo gotcha!'
$ eval echo hi $var
hi
gotcha!
$
Using escape, one can avoid executing the contents of $var:
$ eval echo hi `escape "$var"`
hi ; echo gotcha!
$
A less contrived example is passing arguments to Mail Avenger bodytest commands containing possibly unsafe environment variables. For
example, you might write a hypothetical reject_bcc script to reject mail not explicitly addressed to the recipient:
#!/bin/sh
formail -x to -x cc -x resent-to -x resent-cc
| fgrep "$1" > /dev/null
&& exit 0
echo "<$1>.. address does not accept blind carbon copies"
exit 100
To invoke this script, passing it the recipient address as an argument, you would need to put the following in your Mail Avenger rcpt
script:
bodytest reject_bcc `escape "$RECIPIENT"`

BUGS
escape is designed for the Bourne shell, which is what Mail Avenger scripts use. escape might or might not work with other shells.
