Hello aaditya321,

Please use code tags while using commands or codes in your posts. you can refer the forum rules as following link.
https://www.unix.com/misc.php?do=cfrules

For explaination part of command is as follows.
Code:
sed 's/source text/The text to be replaced with/g -i Input_file

Here s is used because we need to do substitute operation, /Ram/Shyam means to replace word Ram with Shyam, g means to do this subtitute operation globally else it will perform this substitute operation only at 1st match of the word, -i will edit the Input_file and save it too. You can refer the man sed page too for same.

Thanks,
R. Singh

POLISH(5)							      Debian								 POLISH(5)

NAME

       polish - a list of Polish words

DESCRIPTION

       /usr/share/dict/polish is an ASCII file which contains an alphabetic list of words, one per line.

FILES

       /etc/dictionaries-common/words  is  a  symbolic	link  to  a  /usr/share/dict/<language> file.  /usr/share/dict/words is a symbolic link to
       /etc/dictionaries-common/words,	and  is  the  name  by	which  other   software   should   refer   to	the   system   word   list.    See
       select-default-wordlist(8) for more information.

       The directory /usr/share/dict can contain word lists for many languages, with name of the language in English, e.g., /usr/share/dict/french
       and /usr/share/dict/danish contain respectively lists of French and Danish words if they exist.	Such lists should be coded using the UTF-8
       character set encoding.

SEE ALSO

       ispell(1), select-default-wordlist(8), and the Filesystem Hierarchy Standard.

HISTORY

       The words lists are not specific, and may be generated from any number of sources.

       The  system word list used to be /usr/dict/words.  For compatibility, software should check that location if /usr/share/dict/words does not
       exist.

AUTHOR

       Word lists are collected and maintained by various authors.
