program.sh
Code:
source functions.sh
...

if exists "$name";then
	move "$name"
else
	echo "Error: name not here in $c"
fi

...

functions.sh
Code:
$c=1.txt
$v=2.txt

# it checks if $1 is in the file
exists() {
	grep -i -q "^$1$SEP" "$c"
}

#insert info in 2.txt

insert_in_2() {
	local chave=$(echo "$1" | cut -d $SEP -f1)                         

	if exists "$key"; then
		echo "The key '$key' is reg in <1.sh>."
		return 1
	else                                         	                      # new key
		echo "$*" >> "$v"                     			      
		echo "Reg '$chave' added with sucess in <2.txt>."
	fi
	return 0
}

#delete the line in 1.txt and moves the line to 2.txt
move(){
	exists $1 || return
	echo -n "Insert description "
	read description
	
	aux="$(grep -i -v "$name" "1.txt")"  
	insert_in_2 "$aux:$description"
	echo
	echo "The description in '$1' added with sucess!"
		}

This is my code, but it copy the all lines in 1.txt but I only want the line that $name is in! How can i do that?

mlm

FBB::mlm(3bobcat)                                             OFoldStream manipulator                                            FBB::mlm(3bobcat)

NAME

       FBB::mlm - Manipulator modifying left margins of OFoldStream objects

SYNOPSIS

       #include <bobcat/ofoldstream> or
       #include <bobcat/ofoldstreambuf>
       Linking option: -lbobcat

DESCRIPTION

       The  mlm  class  implements  a  manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested
       amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the  request
       then left margin 0 will silently be used.

       Depending  on  the  tab-setting  of  the  OFoldStream  the  inserted value represents the number of blank space characters or the number of
       tab-characters that will be added to the left margin.

       The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream.  If  a
       line  is  still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at
       the next word inserted into that line (cf., the example section below)

       A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.

           int main()
           {
               OFoldStream out(cout, 0, 80);
               out << "hello world (left margin is 0)" << mlm(4) << "
"
                      "this uses a 4 character wide left margin
" <<
                       mlm(-10) << flush <<
                       "left margin -6 changed to 0, active on this line
";
