remote awk syntax problem
Hi there

If i run this command on my Linux box directly, i get the desired result

Code:
[server1] # ipmitool fru | gawk '!NF{f=0}/mb.net0.fru/{f=1}/Product Serial/&&f{print $NF}'
00:AA:4F:A6:A6:C4

however, if i try to run it from a remote server (using SSH) and populating a variable with the result, then i get an error f{print command not found ..note, i had to escape the bang otherwise bash would not even accept the command ..not sure if this is part of my problem, see below, as you can see, it matches multiple instances of "Product Serial". I guess this is down to the the print part of the command not working?


Code:
[server6] # REMOTE_MAC=`ssh server1 'ipmitool fru | gawk '\!NF{f=0}/mb.net0.fru/{f=1}/Product.Serial/&&f{print $NF}''`
bash: f{print: command not found
#

# echo $REMOTE_MAC
Product Serial : 00:AA:4F:AF:2C:45 Product Serial : 0806AL91AE Product Serial : 1506341E Product Serial : 1506251C Product Serial : 15064C21 Product Serial : 15062F16 Product Serial : 15063610 Product Serial : 1506251F Product Serial : 1506561B Product Serial : 15065618 Product Serial : 00:AA:4F:A6:A6:C4 Product Serial : 00:AA:4F:A6:A6:C6
#


now, i thought id try just running it remotely rather than trying to populate a variable, so i tried just ssh'ing the command... still problems


Code:
[server6] # ssh server1 'ipmitool fru | gawk '\!NF{f=0}/mb.net0.fru/{f=1}/Product.Serial/&&f{print $NF}''
 Product Serial        : 00:AA:4F:AF:2C:45
 Product Serial        : 0806AL91AE
 Product Serial        : 1506341E
 Product Serial        : 1506251C
 Product Serial        : 15064C21
 Product Serial        : 15062F16
 Product Serial        : 15063610
 Product Serial        : 1506251F
 Product Serial        : 1506561B
 Product Serial        : 15065618
 Product Serial        : 00:AA:4F:A6:A6:C4
 Product Serial        : 00:AA:4F:A6:A6:C6
bash: f{print: command not found
#

From what i can see, the f{print error, seems to be causing my problems

Does anybody have any idea what i could be doing wrong here, it seems i have tried a huge amount of different variations without any success

any guidance would be fantastic

pbmupc

pbmupc(1)                                                     General Commands Manual                                                    pbmupc(1)

NAME

       pbmupc - create a Universal Product Code bitmap

SYNOPSIS

       pbmupc [-s1|-s2] type manufac product

DESCRIPTION

       Generates  a  Universal Product Code symbol.  The three arguments are: a one digit product type, a five digit manufacturer code, and a five
       digit product code.  For example, "0 72890 00011" is the code for Heineken.

       As presently configured, pbmupc produces a bitmap 230 bits wide and 175 bits high.  The size can be altered by changing the defines at  the
       beginning of the program, or by running the output through pnmenlarge or pnmscale.

OPTIONS

       The -s1 and -s2 flags select the style of UPC to generate.  The default, -s1, looks more or less like this:
        ||||||||||||||||
        ||||||||||||||||
        ||||||||||||||||
        ||||||||||||||||
       0||12345||67890||5
       The other style, -s2, puts the product type digit higher up, and doesn't display the checksum digit:
        ||||||||||||||||
        ||||||||||||||||
       0||||||||||||||||
        ||||||||||||||||
        ||12345||67890||
