You may need to quote the expression. You can also edit files in place with ed.

Thanks for the reply. But this command will just display the term replaced by the new term, not that the changes actually takes place in the file. Even if we redirect the output to a different file this can be done only for one file at a time and also getting back to the original file name is at the cost of another command.

isn't there any way the changes can directly take place in those files?

Thanks in advance

APPLY(1)						    BSD General Commands Manual 						  APPLY(1)

NAME
apply -- apply a command to a set of arguments SYNOPSIS
apply [-ac] [-#] command argument ... DESCRIPTION
apply runs the named command on each argument argument in turn. Character sequences of the form ``%d'' in command, where ``d'' is a digit from 1 to 9, are replaced by the d'th following unused argument. In this case, the largest digit number of arguments are discarded for each execution of command. The options are as follows: -# Normally arguments are taken singly; the optional number -# specifies the number of arguments to be passed to command. If the number is zero, command is run, without arguments, once for each argument. If any sequences of ``%d'' occur in command, the -# option is ignored. -ac The use of the character ``%'' as a magic character may be changed with the -a option. ENVIRONMENT
The following environment variable affects the execution of apply: SHELL Pathname of shell to use. If this variable is not defined, the Bourne shell is used. FILES
/bin/sh Default shell EXAMPLES
apply echo * is similar to ls(1); apply -2 cmp a1 b1 a2 b2 a3 b3 compares the `a' files to the `b' files; apply -0 who 1 2 3 4 5 runs who(1) 5 times; and apply 'ln %1 /usr/joe' * links all files in the current directory to the directory /usr/joe. HISTORY
The apply command appeared in 4.2BSD. AUTHORS
Rob Pike BUGS
Shell metacharacters in command may have bizarre effects; it is best to enclose complicated commands in single quotes (''). BSD
