OK. Thanks m1xram, from what you gave me I have done some work to come up with the script below.
PC3 isn't a clone job but an unzip job followed by a 'create it's vmdisk' job (using vmware-vdiskmanager)
1. This script isn't 100% yet and I appreciate your experienced eyes and advice here.
It works until the second last instruction and that is 7z, which doesn't quite work. It unzips the files to a new subdierctory in the target directory (names %0D). It works when run manually line by line... Please see my hashed out notes at the bottom.
I left out the error checking and messages, mostly because I don't understand them yet (I can interperte though) and also because the files will always be there. I will make sure of that.
2. Once the 7z is fixed (I hope it can be) I want to make another two countries, Ecuador and Chile (with PCs 4, 5 and 6 and PCs 7, 8 and 9 in them) and I planned on having similar scripts for them but can it be done in one, with the "read" command for example or some other fancy way?
Thanks,
D

I have got a temporary working fix for the problem I had. It is not graceful but makes the script 100% functional for what I want.
I would like to understand what is causing the problem with 7z though, if anyone knows?
I am also keen to learn how to improve this and also how I could make the other 2 countries scripts, if I should be making two more country scripts (Ecuador and Chile as mentioned above) like this of if it can all be done in this one.
The fix:
Code:
# First line kind of works
# Line two and three clean up after the first line
7z e "$pc37z" -o"$pc3dir"
mv "$pc3dir/%0D/*" "$pc3dir"
rm -rf "$pcdir%0D/"
for i in "$vmxpc1" "$vmxpc2"; do
echo "Processing \"$i\"..."
done
As 7zip is a port to Linux maybe it does its own command line thing, taking the raw line and parsing it. Although this is unlikely you could try an "eval" command on it to force the issue. Some escaped quotes will also be required for the test. Let me know the result.
Code:
# TEST1: Do variable substitution before execution.
7z_cmd="7z e \"$pc37z\" -o\"$pc3dir\""
eval $7z_cmd
Another thing to try is quoting the parameter with the switch. This is a very unusual thing to do but might work with their parser.
Code:
# TEST2: Do variable substitution before execution.
7z_cmd="7z e \"$pc37z\" \"-o$pc3dir\""
eval $7z_cmd
I'm surprised that the "vmrun" command worked without creating directories for "$vmEngland/pcX". Does "vmrun" create the "pcX" part of the path?
One other note. /var hangs around forever. /tmp gets cleaned up periodically.
The vmrun command does indeed create the target directories, successfully. This is very handy.
I gave up on 7z and just used the unzip command (see second code window below). Of course I first had to unzip the .7z files and re-archive them as .zip for unzip to work.
I also had to create the directories to unzip to. 7zip does that automatically (but not succefully in this case!)
I used /var so that the files would be 'safe' and tucked away for whenever they are needed by the script.
I have searched but cannot find the answer to another question. Maybe you can help me. Can you launch a program (vmware console in this case) at the end of the script and allow the program to carry on running in the background, while the script exits gracefully? In the first code window below is the command to run last thing in the script.
I am also copying it to the desktop in the form of a seperate script file (to double click and click Run), which works.
I thought nohup would help with an & but vmware console doesn't stay open after the script exits...?
From what I understand you can do something like...
Code:
( ( cmd & ) & )
A Linux Guru could explain better why this works but I believe the run-in-background fork that '&' creates detaches from the parent. So I think the first '&' detaches from the process that created it and then next one detaches from the login process. I've tried it without the second set of ()s and it doesn't work so all ()s are required. Some commands know how to do this on their own like dameons.
Usually for scripts where you intend to stay logged in, one '&' is sufficient.
Another way to do this, and I think your goal is to eventually run this from cron periodically, is to spawn off the parallel jobs and wait for them to complete. The simpliest way is...
'wait' waits for all the subprocesses to complete. This might create some confusion in your log files. I tried an experiment with detached processes...
Code:
#!/bin/bash
for x in $(seq 1 $1); do
sleep $2
echo "Proc $$, loop $x"
done
And ran them with...
Code:
./backuptest.sh 5 2 &
./backuptest.sh 10 1 &
...to see what the output looks like and it is a bit yucky. Add a easy to read prefix to your output to differentiate the jobs like "London" or "Manchester" and a timestamp instead of "Proc $$", the process id.
I remember doing a backup job some time ago. The one thing that bugged me was finding files. You create this gargantuan zip or tar gzip file and then want to restore a single file. Searching for that file in the archive is very time consuming unless you also create a directory listing with the archive. The directory listing is much smaller and faster to search. The last part of the zip job could be...
