Question
Converting String Value to Numeric to Percentage
I am trying to read text from a file and convert it to a percentage under Linux shell script.
Sample Input: 0.058324
Output needed: 5.8%
this is what I have been working on:
#!/bin/bash
percentage=`cat /home/username/output.new4
percentage2=$(printf "%-9.3f" "$percentage")
percentage3=$(printf "$percentage2" * 100)
echo $percentage3
Second last line does nothing for some reason
I could use some help. I haven't scripted in awhile.

Try:
#!/bin/bash
percentage=`cat /home/username/output.new4
percentage=`echo "$percentage * 100" | bc`
percentage3=`printf "%-9.3f" "$percentage2"`
echo $percentage3
Note: I've multiplied your initial input by 100, before rounding to 3 decimals, to save the potential loss of precision.
