Help needed with ksh scripting

Hi,

I have written a script which has a line: echo 'VpcId=`grep -w '$2' msbout | grep -w 00005 | awk '{print \$7}'`'

I have done it this way because I want the output of my script to contain: VpcId=`grep -w 9 msbout | grep -w 00005 | awk '{print $7}'`

I have used '$2' instead of $2 so that I can use it as a command line argument and hence get the value 9.

My problem is that the awk part does not get echo'ed properly. The output file has: VpcId=`grep -w 2 msbout | grep -w 00005 | awk {print $7}`.

I don't get the single quotes on the print $7 part of the command.

Can someone please help me out with this. Thanks.

-Yogesh.

I often have to put quotes back into a statement and use sed to do it (see below)


$ echo 'VpcId=`grep -w '$2' msbout | grep -w 00005 | awk +{print $7}+`' |sed "s/+/'/g"
VpcId=`grep -w msbout | grep -w 00005 | awk '{print $7}'`


Note that
1) I don't think you should be escaping the $ in $7
2) I don't have a $2 as I'm running the command from the command prompt

do not propagate such statements
unix really can more|better
this thread is duplicated, assuming the format of the other
eg: 0x0024 2 0x0000 00 009 00005 0x2002
instead of your grep|awk|sed orgie, simply try:
sed -n '/\(.*\) 2 \(.*\) \(.*\) \(.*\) 00005 \(.*\)/\7/p'
that's called: regexp
i don't like '2' and '00005' and would say:
FIRST=" 2 "
SCND=" 00005 "
sed -n "/\(.*\)$FIRST\(.*\) \(.*\) \(.*\)$SCND\(.*\)/\7/p"

note " intead of '
and the spaces in FIRST and SCND
this is an example, on a productive sys i also will be more 'matching'

Not my orgy, but point taken.

Hmmm... still a valid answer of mine too.

I've just need to use that technique (use another character and then sed it to a single quote).
