A Hangman game? Just grep is not sufficient, no. Like Jim already told you, grep can find lines in a file which match a particular pattern, but it just prints them, nothing more. In particular, it doesn't replace characters with other characters; nor does it have loops (other than the input loop for reading in the file, one line at a time, and print those lines which match the specified pattern. If you are really clever you could perhaps use that to drive something ...)
Google for "Hangman source code" or visit the "99 bottles of beer" site.

For eg: int a,b,c,d,a;

Is there a way to print only the lines where the variable name occurs more than once, using grep... (1 Reply)

zfgrep
ZGREP(1) BSD General Commands Manual ZGREP(1)
NAME
zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files
SYNOPSIS
zgrep [grep-flags] [--] pattern [files ...]
zegrep [grep-flags] [--] pattern [file ...]
zfgrep [grep-flags] [--] pattern [file ...]
DESCRIPTION
zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).
The grep-flags and pattern arguments are passed on to grep(1). If an -e flag is found in the grep-flags, zgrep will not look for a pattern
argument.
zegrep calls egrep(1), while zfgrep calls fgrep(1).
EXIT STATUS
In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.
SEE ALSO
egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
