I am getting the following error message:

I also want to count the number of pids that are killed and append the results to a text file. I am new to shell script programming.

1.The first part of code is exporting a text file column containing ppids.

pid.txt contents are as follows:

Code:
Ppid
5569000
6789034
4567890
1234567
5678908
3457892

2. The second part of the code changes permission on the PpidFile

3. The third part of the code loops through the column in the text
file and kill each Ppid.

4. finally a line of text is appended to a text file. The text contains the total number of pids killed and the date.


Here is my code:
Code:
export PpidFile="/path/to/pids.txt"
if [[ -f "$PpidFile" ]]
then
	/bin/chmod 755 $PpidFile
	Ret=$?
	if [ 0 -eq $Ret ]
	then
		for RelatedEachPid in `/bin/grep -v "Ppid" $PpidFile | /usr/bin/tr "\n" " "`
		do
			/bin/echo "kill -9 $RelatedEachPid"
			/bin/kill -9 $RelatedEachPid
			Ret=$?
			if [ 0 -ne $Ret ]
			then
				/bin/echo "kill -9 $RelatedEachPid Fail"
			else
				/bin/echo "kill -9 $RelatedEachPid 
PIDkill"
			fi

echo "total of pids killed: wc-l $PIDkill -  $date" >> pidkill.txt

Mod Comment PLEASE use CODE tags for sample input and output as well as for code segments (as you have been asked to do before).
What shell are you using?

There is no reason to export a variable that you are not passing to another shell execution environment.

There is no reason to make a file that does not contain any executable text executable. Consider changing:
Code:
if [[ -f "$PpidFile" ]]
then
	/bin/chmod 755 $PpidFile
	Ret=$?
	if [ 0 -eq $Ret ]
	then	...

to something more like:
Code:
if [ -r "$PpidFile" ]
then	...

There is no need for the tr command in your command substitution. And a:
Code:
while read RelatedEachPid
do	if [ "$RelatedEachPid" = "Ppid" ]
	then	continue
	fi
	...
done < "$PpidFile"

would be much more efficient than:
Code:
for RelatedEachPid in `/bin/grep -v "Ppid" $PpidFile | /usr/bin/tr "\n" " "`
do	...
done

There is no done terminating your for loop.

There is no fi terminating your 1st two if statements.

There is nothing that sets the variables PIDkill and date before they are used.

It looks like you might be trying to count the lines in the file named by the variable PIDkill with the command:
Code:
echo "total of pids killed: wc-l $PIDkill -  $date"

but printing the string wc-l - won't do that. If you had set PIDkill to the pathname of a file, then something more like:
Code:
echo "total of pids killed: $(wc -l $PIDkill) -  $date"

might come closer to doing what you seem to be trying to do.
