Awk and read bailing out
Hi All,

Can some body help me in this to work
Code:
#!/bin/ksh

    nof=`wc -l outFile_R.out | sed -e 's/[a-zA-Z_. ]*//g' `
    no_of_lines=`expr $nof - 0`
    z=1
    while [[ $z -le $no_of_lines ]]
    do
    cat outFile_R.out | awk -v I="$z" 'NR==I { print $0 }' | read from_date to_date id
    echo "executing $from_date $to_date $id"
    z=$((z + 1))
    done

output required if no_of_lines = 2

executing 2010-01-01 2010-01-31 1

Hi sol_nov,

I noticed it may be possible to further simplify your script to something like this.
Code:
while read from_date to_date id
do
  echo "executing $from_date $to_date $id"
done < outFile_R.out

Perhaps that could be of use to you...

On Solaris it's generally better to use /usr/xpg4/bin/awk or nawk and not /usr/bin/awk

If you see this: awk: syntax error near line 1 awk: bailing out near line 1 Chances are you are working on Solaris and you are using standard awk. If so, you need to use /usr/xpg4/bin/awk instead, which is POSIX awk (or nawk if that is not available). (1 Reply)
