running rsh from windows xp

[joeljoel]

we are running rsh from windows xp pro to hpux 11.00

the exact command is this:
rsh hpux01 -l root /scripts/backup.ksh
which runs the script pasted below.

question: why does the lvsplit fail? when we run this from a normal shell, it works fine ... i thought it may be the env is not (and it may be the case) but when it view the env via "rsh hpux01 -l root env" it looks ok

Hi,
could you please include a copy of your log messages (wlog) that makes you suspect lvsplit is failing.

[joeljoel]

the errors:

splitit[5]: lvsplit: not found
splitit[13]: fsck: not found
splitit[21]: mount: not found

since these are obviously a *simple* pathing issue, i guess i could hardcode the path in the script unless there's a way to source the running user's profile via windows rsh (something like: ". ./.profile" )

also after closer inspection, the "rsh hpux01 -l root env" shows an environment that does not match the normal (telnet) shell (i.e. under sh, PATH=abc:xyz under rsh, PATH=abc)

thanks,
joel

Hi,
so it seems to be a env problem. Have you tried including your env file into the script?

[Torsten.]

Please use full path names for clean programming, e.g.:

/usr/sbin/lvsplit
/usr/sbin/mount

to find the binary use "whereis" or "whence"

# whence mount
/usr/sbin/mount

[joeljoel]

thanks for the help

i specified the path to the bin files and everything is OK

i thought of that before and had not yet tried it primarily because the "env" command via rsh indicated that it would see the bin files

regardless - it's fixed
