Scripting issue : Can not read the second line

Dewa Negara_4 — Tue, 25 Oct 2005 03:28:16 GMT

Hi All,

I have a simple script using while read command below. When I tried to run it, it only run for first line (bdsn4013 SECU). It can not go to the second line,etc. Anyone can help to tell me what the issue is?

Please help. High score will be given.

Thanks and Best Regards,
Dewa

Is the every line in file seperated by new line??

od -c < your_file

Dewa Negara_4 — Tue, 25 Oct 2005 03:46:55 GMT

Thanks.

I tried to use both "space" and "tab". Both gave me the same (while read can not go to the second line).

Thanks.

What does following give??

How many lines do you get?? Post.

Re: Scripting issue : Can not read the second line

RAC_1 — Tue, 25 Oct 2005 03:59:03 GMT

What does following give??
grep -v "#" $LIST|grep -v "^$"

Also as follows.
grep -v "#" $LIST|grep -v "^$"|od -c

Hi Dewa,

I haven't read through your lengthy script to check for any possible errors there.
But despite I assume it's only the grepping part that reads the input lines.

How about trying something like

grep '^[^#]' $LIST | while read CLN PKG; do

at the beginning?

Hi Rac,

Sorry...what you mean?

When I tried to run the script, it only reads the first line. It never goes to the second line. Is there any problem with the config file /var/opt/secu/parmlib/transfer_sched.dat?

[root@bdhp4337:/var/opt/secu/parmlib]
# more transfer_sched.dat
bdsn4013 SECU
bdsn4002 SECU_QA
bdsn4014 SECU

[root@bdhp4337:/var/opt/secu/scripts]
# ./transfer_secu_DEV.sh
251005 bdsn4013 COMPLETED

Expected result as below:
# ./transfer_secu_DEV.sh
251005 bdsn4013 COMPLETED
251005 bdsn4002 COMPLETED
251005 bdsn4014 COMPLETED

Hi Ralph,

Thanks. It gave me the same result.

RAC_1 — Tue, 25 Oct 2005 04:20:21 GMT

I saw the remsh statement.
if [ `remsh $CLN uname -s 2> /dev/null|grep -e SunOS -e | -e HP-UX |wc -l` -lt 1 ]then echo "$DATE $CLN FAILED Either hostname is incorrect or remsh is not working from bdhp4337." |tee -a $LOG;continue;fi

Why not simplify it??

count=$(remsh $CLN 'uname -s 2>/dev/null'|egrep 'SunOS|AIX|HP-UX|wc -l)
if [[ ${count} -lt 1 ]];then
your_code here

Hi Rac,

Thanks. I have modified it. It still gave me the same problem.

Thanks.

RAC_1 — Tue, 25 Oct 2005 04:47:55 GMT

set -vx and run the script. check the output carefully and you should be able to point out.

Sandman! — Tue, 25 Oct 2005 08:25:37 GMT

Dewa,

Run your script at the command line with debugging on.

# sh -x <script_name>

What's meant by "When I tried to run it, it only run for first line (bdsn4013 SECU). It can not go to the second line,etc." Please clarify?

regards!

Hi,

I think the remsh-line is your problem:
if [ `remsh $CLN uname -s ...

remsh will read from stdin normally - change to 'remsh -n' so remsh will no try to read from stdin and so the second line will not be 'eaten'.

Al Langen_1 — Wed, 26 Oct 2005 09:09:33 GMT

So, what does this line do?

bdsn4013 SECU

Does it finish?

Turn on script and run it with set -x
