starting a script

[Maciej Szewczykowski]

hi all,
i'd like to ask for help in the following matter:
i have a script that contains several standard commands. among them there is a command that is supposed to start another script - it is just a name of the script that is to be initialized, actually. but it doesn't work this way.
how to make it work?

[Pete Randall]

Have you used the full path name to the second script?

Do you have the PATH variable set in ht script to allow the command to be "reached"? ohterwise, are you specifiying ht full pathname of the script?

[T G Manikandan]

Make sure

1.Execute permissions of the script

2.Provide the full path of the script.

Thanks

[Maciej Szewczykowski]

of course, i've given the full path and set permission properly - still nothing.

hi,

can you post the scripts or part of them?

caller and callee

You may wish to trace it using "echo" messages at specific parts in the code.

thanks

[Pete Randall]

Well, of course, given the lack of info provided, we had to eliminate the obvious. Thanks for your patience. Maybe if we could see the script, we'd have more insight.

here goes the script - please take a look at 9th line: here is invoked the script (rem_arch) supposed to be run.

[melvyn burnard]

try adding the line :
set -x
to hte beginning of the script and then watch the output.

[Pete Randall]

I'm not sure what this script is doing:

$ man put
No manual entry for put.
$ man lcd
No manual entry for lcd.
$ man mget
No manual entry for mget.

Maybe some sort of ftp script, I guess? How is it invoked?

Pete

[Maciej Szewczykowski]

what does parameter -x cause?

[Dario_1]

Try running the script in debug mode:

sh -x scriptname

You will the script executing every command.

yes indeed Pete - actually it is an input file for initializing ftp connection
ftp < script
so the commands are carried out by remote host

[Yogeeraj_1]

hi,

This is a "debugging-tool". After this command is executed, all further commands will be
printed to the terminal before they are executed until a 'set +x'
command is found.

[Pete Randall]

Ok, can you tell if the mkdir and the put(s) were successful? The last line removes all the evidence so maybe if you commented it out and then checked to make sure things are as you expect.


Pete

[Maciej Szewczykowski]

thank you all.
in which line of the script command set -x should be placed?

[Yogeeraj_1 · Accepted solution]

hi,

if you can't mix ftp commands with shell commands!

this should provide you with some hints:

...
for i in `cat ftp.list`; do
echo "put $i"|ftp serverB
file=`basename $i .txt`
mv $i $FTP_ARCH/
done
...

[Maciej Szewczykowski]

yes Pete, all the commands are successful, except the one invoking the script.

[Yogeeraj_1]

set -x should be place at the position from which you wish start the debugging process.

you stop with a "set +x"

You seem to be combining ftp and shell script commands together! You can't do that.

I'm assuming this is the command thats not working:

/usr/local/home/rainbow/archiwum/temp_arch/rem_arch


If this is on the local host (the host where ftp is being run from) then you could just add an exclamation mark at the start to run it in a shell:

!/usr/local/home/rainbow/archiwum/temp_arch/rem_arch

If this command is actually on the remote host ( the one you are ftp'ing to) then there is *no way* to run it from within ftp as it doesn't allow you to run code on the remote end.

How about the contents of the remote script, could we see that? I'm thinking maybe it is invoked but unable to do anything for some reason. Maybe you could put a touch command in the remote script, then the existence of the "touched" file would prove that the script is being invoked.

[Maciej Szewczykowski]

thanks a lot, Yogeeraj. it seems that the problem's gone.
till the next one.

[Pete Randall]

Yeah, that's where I was trying to go, Duncan - thanks. The script is never getting invoked.

Hi,

Sorry to be the bearer of bad news, but you can't run shell scripts on the remote system via ftp.

The script you have supplied is a list of ftp commands and will be executed within ftp.

If you need to run the shell script on the remote system you'll need to use remsh or something similar.

regards,

Darren.

[Yogeeraj_1]

hi,

For running remote commands, you may consider following command will return immediately without waiting for the remote command to complete:

remsh otherhost -n "command 1>&- 2>&- &"
