I have a problem !!
There is a shell script "xyz" :
=========
#!/bin/sh
find / | filter | cat
=========
I call it with : ./xyz
When I kill the script with "kill PID" then
the pipe that was called inside the script is still runing.
My question is how to get the pipe killed automatically by killing the
script!!
Thanks a lot !!! Martin
1. a question about 'read' from pipe in shell script
Hi, all,
i am stuck with 'read' in my shell script, and could figure out why it did
not work, here is my simple script:
------------------------------------------
#!/bin/sh
ORACLE_HOME=/apps/oracle/product/8.1.7
if [ `uname` -eq SunOS ]; then
echo "Inside"
/usr/ccs/bin/size $ORACLE_HOME/bin/oracle | /usr/bin/awk '{print $1}'
|read mtext
fi
echo $mtext
-------------------------------------------
when i run this script, i get:
dev:sql%sh mem_size.sh
Inside
From command line, when i use 'size', the output is:
eds-xml-dev:sql%size $ORACLE_HOME/bin/oracle
27221933 + 267676 + 21060 = 27510669
eds-xml-dev:sql%size $ORACLE_HOME/bin/oracle | awk '{print $1}'
27221933
So it seems 'read' doesn't want to read anything from pipe, could somebody
shed light on this? thanks.
Mike
