extra space issue with awk
Code:
for diskname in $(lspv |awk '{print $1}')
do
lquerypv -h /dev/|awk '/'$diskname'/ { print ; exit }'
doneNo output is returning from the loop. I think awk put an extra space to the command - lquerypv -h /dev/ so that the command is executed as i.e. lquerypv -h /dev/ hdisk230 with a space between /dev/ and hdisk230. Please advise how to remove an extra space in this case if my guess is correct. Thank you |

Do: Code:
lspv |awk '{print "="$1"="}'so you don't have to guess

Code:
lspv |awk '{print "="$1"="}'returns the outputs with = Code:
=hdisk0= =hdisk1= =hdisk113= ... Code:
lspv |awk '{print "/dev/"$1}'gives me like this: Code:
/dev/hdisk0 /dev/hdisk1 /dev/hdisk113 ... It looks good so far, but if I put in Code:
for diskname in $(lspv |awk '{print "/dev/"$1}')
do
lquerypv -h |awk '/'$diskname'/ { print ; exit }'
doneI am getting errors: Code:
Syntax Error The source line is 1.
The error context is
//dev/hdisk0/ >>> { <<<
awk: 0602-500 Quitting The source line is 1.
Syntax Error The source line is 1.
The error context is
//dev/hdisk1/ >>> { <<<

Try: Code:
for diskname in $(lspv |awk '{print $1}')
do
lquerypv -h /dev/|awk -vx=$diskname '$0~x{ print ; exit }'
done |

Are you sure this command is giving proper output? (containing disk names?): Code:
lquerypv -h /dev/ |

The command has to be: Code:
lquerypv -h /dev/hdisk# // please note no space on Code:
/dev/hdisk# hdisk# comes from Code:
'/'$diskname'/ { print ; exit }'It looks to me that i.e. Code:
lquerypv -h /dev/ hdisk0 (please note a space) is executed. Please advise. |
