#!/bin/sh
echo "one"
read host
echo "two"
read ip
echo "three"
read oid
read oid
echo $oid $host >> logger.txt
it never makes it to echoing "two"
No matter if I pass parameters (this is to receive SNMP traps, and the parameters come) manually in any varied way.
EDIT: This has permissions etc etc, I am testing it by launching it manually, "one" is echoed.
read waits for input from STDIN.
If you do not insert any input by hand (in a interactive terminal) or you do not provide any input from STDIN like this:
echo -e "my_host\n192.168.1.100\nfoo\nbar" | ./myscript
it will hang waiting for input
In the example \n is a newline.
If you want to access parameters, do not use read, but the $1...$n variable.
./myscript my_host 192.168.1.100 foo
You need this:
#!/bin/sh
host=$1
ip=$2
oid=$3
echo $oid $host >> logger.txt
read actually waits for user input.
read host will wait for a user to enter any data till he presses the return key and what ever the data user enters will be stored in host.
readreads from standard input, and it blocks until it receives that input; so by "ends", do you mean "hangs"?yourscript.sh HOST_NAME IP OID OID
