Question

for INSTANCE in $INSTANCES
do
  ssh weblogic@${SERVER} "egrep \"^$SEARCHHOUR1:$SEARCHMIN1.*DEBUG.*LONG QUERY.* ms.\$|^$SEARCHHOUR2:$SEARCHMIN2.*DEBUG.*LONG QUERY.* ms.\$\" vgprod1/mw.log.$INSTANCE  | awk '{ $(NF-1)>=10000 }' "
done

Error:

NF-1: command not found
awk: cmd. line:1: { >=10000 }
awk: cmd. line:1:   ^ syntax error

I am getting the above error while executing on a Unix server. I guess I am missing backslash at some places in AWK. How can I fix this?

Answer 1

As noted by sarathi, your problem is an unquoted $.

It might be easier to spot if you split up the command:

pattern="^$SEARCHHOUR1:$SEARCHMIN1.*DEBUG.*LONG QUERY.* ms.\$|^$SEARCHHOUR2:$SEARCHMIN2.*DEBUG.*LONG QUERY.* ms.\$"

for INSTANCE in $INSTANCES
do
  ssh weblogic@${SERVER} "egrep '$pattern' vgprod1/mw.log.$INSTANCE  | awk '\$(NF-1) > 1000'"
done

Also note that egrep '$pattern' will be expanded correctly when it is enclosed in double quotes.
