Shell Programming and Scripting

Hi evryone
i need a help .

i have a file xcv.the content is :

accelerate

i want a script which will run 1000 times in loop and changing the value to

accelerate to
acceler

in 1st loop and in 2nd loop it will be again

accelerate and so on .

2

Requirement not clear. 1000 times to change accelerate to acceler?

regards,
Ahamed

yes ....1000 times to change accelerate to acceler?

You can try using sed option...inside for loop

sed 's/accelerate/acceler/g' inputfile

Thanks

sed 's/accelerate/acceler/g' inputfile
by this i can get value "acceler" in 1st loop but in 2nd loop i wantreverse

The example you're giving for this question is so absurd I have to ask: is this homework?

So you need to check the current state and act differently depending on the current state

if accelerate=$(grep accelerate inputfile); then 
   sed 's/accelerate/acceler/g' inputfile
else
   sed 's/acceler/accelerate/g' inputfile
