Shell Programming and Scripting

I like that consequent application of arrays; that might simplify my approach and even offer simple extensions...

Thanks for the other approach, I really appreciate you both taking the time to give an example, I am going to play around with both of these and see what I can come up with

So messing around with both Methods I have come to find out that "Stat" does not work with the Version of AIX I'm on but Instead I must use "wc"
So I have improvised on the line

Code:

set -A FS$i $(ssh ${HOSTS[i]} "wc -c ${FILES[@]} | awk '{print $1}'")

I have tested the line starting with ssh and it works just fine but when running the Script i get the following error

Code:

"i++: 0403-053 Expression is not complete; more tokens expected

" I'm almost positive that line is the issue as it goes to ssh, pulls the server disclaimer but continues no further. I have tried putting the command in Double Quotations as Well as the

Code:

'{print $1}'

in double apostrophes, not sure what I'm still missing here?

Does your ksh version understand the (( ... )) "Arithmetic Expansion"?
Did you check for the istat command?
Did you assess using ls -l's size field (one inode access) against counting every single byte in a file?

Code:

set -A FS$i $(ssh ${HOSTS[i]} "wc -c ${FILES[@]} | awk '{print \$1}'")

Code:

i=0 while [[ $i -lt ${#HOSTS[@]} ]]; do    set -A FS$i $(ssh ${HOSTS[i]} "stat -c%s ${FILES[@]}")    ((i++)) done

Is this not the problem for ksh? I will have to give that a shot.

Code:

set -A FS$i $(ssh ${HOSTS[i]} "wc -c ${FILES[@]} | awk '{print \$1}'")

Whats The Significance of the Back Slash here?


as for the Version of Ksh, I'm pretty sure it predates the paleolithic era, as for the the istat (inode) command I have not tried that, looked at it previously but couldn't find any sort of modifiers or description on how to extract just the file size from IBM's site so wasn't positive that was an option. and for assessing the "ls -l" are you referring to something like this?

Code:

$ set -A FS$i $(ssh ${HOSTS[i]} "ls -lah ${FILES[@]} | awk '{print $5}'")

Moderator's Comments:

Please use code tags NOT quote tags around code. Thank you.

Same problem as before. Without escaping, $5 will evaluate before ssh happens.

Code:

set -A FS$i $(ssh ${HOSTS[i]} "ls -lah ${FILES[@]} | awk '{print \$5}'")
