Also, never use \n \t etc in echo. You can use them in printf, which has unique restrictions of its own. For your purposes, printf "%s\n" "string" is equivalent to echo "string". Put extra newlines in the first part, not the second part, if you need them.

Note that v1_file/* won't expand recursively. It'll fill in the lowermost directory tree and that's it.

My first try:

Code:

func_grep() {
        read cmdstr cmd_opt search_key # Read arguments from keyboard, separated by space

        check_str "$cmdstr" || return 1 # Return immediately on error

        expandstr "$cmdstr"

        [ -d "$v1_file" ] && v1_file="$v1_file/*" # Expand dir

        # $v1_file can't be quoted for * to work, everything else should be quoted.
        "$search_cmd" "$cmd_opt" "$search_key" $v1_file > "/ercs/ercs000/reports/grep_$LOGNAME"

        case $? in
                0) printf "\n%s\n" "The grep output file: /ercs/ercs000/reports/grep_$LOGNAME has been created." ;;
                1) printf "\n\t%s\n" "No matches were found." ;;
                *) printf "\n\t%s\n" "Syntax  errors  or  inaccessible  files."
                        printf "\t%s\n" "$search_cmd $search_key $v1_file"
                        return 1 ;
        esac
}

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

	   1.	  Variable assignment lists preceding the command remain in effect when the command completes.

	   2.	  I/O redirections are processed after variable assignments.

	   3.	  Errors cause a script that contains them to abort.

	   4.	  Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a
		  variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file  name  genera-
		  tion are not performed.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
