vname1='str'
vname2=1
echo $vname1
while(( $int<=100))
do
echo $int
let "int++"
done

Suppose we name out script as myscript.sh, to run it, fisrt we givie it permission:
1

|
$ chmod 755 myscript.sh
$ ./myscript.sh

Some some techniques (more will be added):

NAME="John"
echo "Hi $NAME"
echo 'Hi $NAME'
git commit; git push
git commit && git push
git commit || echo "Commit failed"

echo start creating files
int=1
while(( $int<=25 ))
do

int=1
while(( $int<=25 ))
do
echo $int
dd if=/dev/urandom of=test/tt$int bs=1000 count=60
