Script question

[Hunki]

I am using rcp to copy files from one server to another , I want to add a confirmation in it that the file copied successfully. How do I do that.

thanks,
hunki

Hi hunki,

after statement with "rcp" test the comand with
lines like this :

if [[ ${?} -eq 0 ]]
then
echo "remote copy OK"
else
echo "remote copy KO"
fi

I dont beleive rcp itself offers any kind of verification mechanism.

When the copy is complete, you can run "cksum" command against the source and target files and compare the output.

Hey

my post with the checksum part.

As noted the $? variable will hold the return value of the rcp command. Though this may return 0, that doesn't necessarily mean the copy process was 100%. You would need to do a file comparison in order to know that the files are truly successfully copied.

you also need to be aware that if the destination is a different platform, checksum may not give you the answer you're looking for.

For example, an ascii file copied to windows is going to result in a different size and different chksum simply because of CR -vs CR/LF issues.

Still I would require more of a one line command.

Exmaple :

rcp host:/tmp/abc .
#Need to verify here with an output message.
# and then continue with next rcp.
rcp host:/tmp/xyz .

Please suggest.

rcp *doesn't* provide any messaging when thing work. return codes may / may no be a valid indication, i haven't tested this

Hi,

a kind of 'brute solution' is to transfer the file back again and do a local check:

flist='f1 f2 ...'
rm -f tmpfile$$
for fil in $flist
do
if rcp $fil remhost:/path/name
then
if rcp remhost:/path/name/${fil##*/} tmpfile$$
then
if cmp -s $fil tmpfile$$
then :
else print -u2 file $fil with verify error; break
fi
else print -u2 file $fil with get error; break
else print -u2 file $fil with put error; break
fi
done
rm -f tmpfile$$
