yes of course.

Is there something more clean but readable :

Code:
my_function () {
CMD="COUNT=\$(sed -n '/^$1/,\$p'  $2 | sed -n '/^$3/,\$p' | sed '/$5/ q'  | sed -n '1p' | grep -c '$4'   )"
eval $CMD
if [[ $COUNT -gt 0 ]] ; then
    return 0
else
    return 1
fi
}

Code:
asus:~ # my_function  "In the Linux startup process"  "/root/Documents/file_text.txt" "Like init" "manage" "ways"
asus:~ # if [[ $? -eq 0 ]] ; then 
> echo "success"
> else 
> echo "failed"
> fi
success
asus:~ #

Code:
asus:~ # my_function  "In the Linux startup process"  "/root/Documents/file_text.txt" "Like init" "blablabla" "ways"
asus:~ # if [[ $? -eq 0 ]] ; then 
> echo "success"
> else 
> echo "failed"
> fi
failed
asus:~ #

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
