Concatenating asterisks in bash

Question

I am trying to concatenate asterisks (*) to a string variable. However, I keep getting the files in the current directory instead. I have tried

row+='*'
row+=$row     #where row is *
row='*'"$row"
row="\*$row"
row="${row}*"

etc.

row='*'."$row"  #produces *.*.*. 

I thought \ would escape the *, but it didn't work.

Answer 1

Try using quotes around the variable before you "print".

For example:

cronSen="*/$a * * * * bash /etc/init.d/ckDskCheck.sh"
echo "$cronSen"

This could work. I got the idea from here: Printing asterisk (*) in bash shell
