hi ecasadella,
thanks for ur reply... but i still couldnt get the pid of ftp process alone... heres the ftp process which comes inside my script.
echo ftp -inv \<\< ! > ./tmp5
echo open >> ./tmp5
echo user uname pwd >> ./tmp5
echo cd /tmp/tmp1 >> ./tmp5
echo get file1 >> ./tmp5
echo quit >> ./tmp5
chmod 744 ./tmp5
./tmp5 > ./tmp66
and to get PID I use,
echo $$ >! ./myftppid and put it in a file....
this above line I put it above the ftp process.. but it just gets the PID of this whole script rather than that ftp process alone...
now how should i use the ptree... ur help appreciated..

once you are in the ftp session, try this:
ftp> !ps | grep ftp
or additionally
ftp> !ps | grep ftp | awk '{print $1}' > myftppid

Tell me what OS are you using?
besides try this:
ftp -inv << EOF > ./log
user uname pwd
!ps | grep ftp > ./myftppid
cd /tmp/tmp1
get file1
quit
then treat myftppid as you wish

here it is.. but i think something is wrong.. can u pls let me know..
echo ftp -inv \<\< ! > ./tmp5
echo open >> ./tmp5
echo user uname pwd >> ./tmp5
echo !ps | grep ftp | awk '{print $1}' >! ./myftppid
echo cd /tmp/tmp1 >> ./tmp5
echo get file1 >> ./tmp5
echo quit >> ./tmp5
chmod 744 ./tmp5
./tmp5 > ./tmp66

echo open >> ./tmp5
echo user uname pwd >> ./tmp5
echo !ps | grep ftp | awk '{print $1}' >! ./myftppid
echo cd /tmp/tmp1 >> ./tmp5
echo get file1 >> ./tmp5
echo quit >> ./tmp5
chmod 744 ./tmp5
./tmp5 > ./tmp66

With this example you just execute the code in your script, and every message will be logged into tmp66
Try to replace those lines with these:
#!/usr/bin/ksh
FTP_USER=user
FTP_PASS=password
ftp -inv << EOF > ./tmp66
user $FTP_USER $PASS
!ps | grep ftp > ./myftppid
cd /tmp/tmp1
get file1
quit
please avoid to redirect >! , is ther a reason why you are doing this ?

ok, to do this you can put this code in a separate script, so that whenever you need to execute it from your c-shell just add this line in your csh script:
ksh ftp_script.ksh
and if you need to pass user and password to the script, do it as common script args like:
ksh ftp_script.ksh $user $pass $host
so in the ksh script you must set them as:
USER=$1
PASS=$2
HOST=$3
once this script finish its execution the c-shell script will keep parsing its own lines.

that's why G-ds created interpreter directives - being on the first line of the "interprative" script - it 'directs' the calling process to use a given/specified interpreter [shell, perl, ruby etc] for the rest for the context of the file.
In your example you should have the following on the FIRST line of your script:
#!/bin/ksh vlad
+---------------------------+
|#include<disclaimer.h> |

I just don't get it, I execute this script in my machine on a Solaris 7 with csh and it works perfectly, try to isolate this code into a separate script and tell me step by step what you are doing. EDC

hi ecasadella, below is the script which i'm trying to do.. this script runs every 15 minutes and ftp's to a site to get files... sometimes the ftp session hangs up.. so before invoking this script next time i've to chek whether the previous ftp is still running or not.. if running i've to kill that ftp and start a new one... thanks for your help all the way from y'day...
#!/bin/csh
if ( -f ./myftppid ) then
set oldpid = `cat ./myftppid`
ps -p $oldpid | egrep "ftp" ; set stat = $status
echo $oldpid
while ( $stat == 0 )
# Last invocation of the script still running....
@ x ++
if ( $x == 10 ) then
# tried 10 times to kill it and it wouldn't die
echo "Couldn't kill old process"
echo " "
exit 5
endif
echo "Old FTP still running "
kill -9 $oldpid
sleep 1
ps -p $oldpid | egrep "ftp" ; set stat = $status
end
endif
# put the PID in a file so we can check it next time we start
#echo $$ >! ./myftppid
