[Chester LUG] Help with a bash script

[Stuart Burns]

Lol, The money for the tea and coffee funds, easier to use the blank cheques
lying around ;)

No, the purpose is to act as a (poor) interface between a MUMPS (aka Cache
Intersystems) DB and an IBM iSeries.

The files concern stock that needs to be reserved and passed from the
iSeries to the MUMPS system. So basically the iSeries drops a text file at
random intervals onto the FTP server and then the FTP server via the batch
script translates it into the correct format.

However I have discovered that numbering, as long as it is mmdxxxx where x
is unique, is fine. The RS at the beginning has special meaning in as much
as it is indicates a certain type of transaction. I therefore got the
required level of uniqueness by tacking %N on the end of the date var.

The final code I came up with (yet to be tested) is

mount //10.0.0.133/mumps /mnt/mumps -o username=xxx,xxx
cd /home/myftpusername/
DATE=`date +%m%u%N`
mv RS000001.001 RS$DATE.001
cp RS$DATE.001 Reserve/Backup/
mv RS$DATE.001 /mnt/mumps/DATA/DATA_OUT/
umount /mnt/mumps

And thanks to everyone who suggested an answer. I will have to take a look
at printf - looks a powerful command!
