Rename Files By Bash Script Automatically

Here is a bash script helps you to rename files *.c.gz to new files *.c.

Code snippet:

#! /bin/bash
cmd1=$(ls |grep c.gz)
cmd2=$(ls |grep c.gz |sed 's/\.gz//g')
array1=()
len1=0
for i in $cmd1; do
    array1[$len1]=$i
    len1=$(expr $len1 + 1)
done

array2=()
len2=0
for i in $cmd2; do
    array2[$len2]=$i
    len2=$(expr $len2 + 1)
done

for(( i=0;i<$len1;i++)); do
    echo ${array1[$i]}"==>"${array2[$i]}
    mv ${array1[$i]} ${array2[$i]}
done

Run it in the terminal.
