Hi All, Can anyone help me with the following script problem please its driving me nuts. I am trying to make a script capable of commenting and uncommenting lines on a custom config file similar to this. myconf: #Months 02 04 06 #08 10 12 myscript.sh: #!/bin/bash echo "Enter a number from 1 - 10 to sed" read i NUM=`expr $i - 2`; printf %02d $NUM ; echo " " echo "I will sed this " $NUM read sed '/$NUM/s/^#//' myconf > newconf When you enter the number 10 you lose the decimal point after the expr sum subtracts 2 it is still 08 but on the sed I think it uses 8 not 08 so the sed line fails Is there another way to do this? Any other methods would be welcome.
once you add `` ' `` single quote shell will not recognize the variable , I had this problem the only way I found is to use "sed -f" and generate sed scripts on the run time on temp dir then run sed -f . example cat << EOS sed statments $NUM sed statments
num.sed
sed -f num.sed rm -f num.sed hope this will help,I think there is smart way to do it.
