Can anybode suggest me where to find the source code for system calls itself?
Download the libc source code of the appropriate system. You'll find libc sources for Linux, bsd and Solaris on the net.

When ever we quit a file or save and quit a file,
Give some context. Quit and save aren't system calls either. Do you mean typical commands from the file menu? No. The application calls close(). The OS itsself takes care about writing the actual data to disk. Typically it won't write the contents to disk immediately but just send them to some buffer which is cleaned whenever the disk comes idle or the filesystem is unmounted.

NAME
lessecho - expand metacharacters SYNOPSIS
lessecho [-ox] [-cx] [-pn] [-dn] [-mx] [-nn] [-ex] [-a] file ... DESCRIPTION
lessecho is a program that simply echos its arguments on standard output. But any metacharacter in the output is preceded by an "escape" character, which by default is a backslash. OPTIONS
A summary of options is included below. -ex Specifies "x", rather than backslash, to be the escape char for metachars. If x is "-", no escape char is used and arguments con- taining metachars are surrounded by quotes instead. -ox Specifies "x", rather than double-quote, to be the open quote character, which is used if the -e- option is specified. -cx Specifies "x" to be the close quote character. -pn Specifies "n" to be the open quote character, as an integer. -dn Specifies "n" to be the close quote character, as an integer. -mx Specifies "x" to be a metachar. By default, no characters are considered metachars. -nn Specifies "n" to be a metachar, as an integer. -fn Specifies "n" to be the escape char for metachars, as an integer. -a Specifies that all arguments are to be quoted. The default is that only arguments containing metacharacters are quoted SEE ALSO
