This will replace each occurrence of fdasatavol with fdasatavol_sata: 

sed 's/fdasatavol/&_sata/g'

If your input has occurrence of fdasatavol that are not in /fdasatavol/ankit and you don't want to substitute these then use:

sed 's@/fdasatavol/ankit@/fdastatavol_sata/ankit@g'

Note: you can use any character as sed's delimilter to aviod the confusion with the parrtern contiaing /. sed prints to stdout by default, if you are happy with the changes produced by sed you can use the -i option to store back to the file.

sed -i 's/fdasatavol/&_stat/g' file

to write to a new file (without modifying file1):

sed 's/fdasatavol/fdasatavol_sata/g' file1 > file2

or to replace in the original file:

sed -i 's/fdasatavol/fdasatavol_sata/g' file1
