how to program in shell to get a part of a file by line number

[George2]

Hello everyone,


I am wondering how to program in shell to get a part of a file by indicated (input) line number, for example, get from line 100 to line 200 in a specific file.

What command(s) should I use?


thanks in advance,
George

$ # first 10 lines
$ head foo.c
void f1 ( void **p ) {
    *p = 0;
}

void f2 ( ) {
    int *p1;
    void *p2;
    f1( &p1 );
    f1( &p2 );
}

$ # a subset of lines
$ sed -n '7,9p' foo.c
    void *p2;
    f1( &p1 );
    f1( &p2 );

Cool, thank you Salem!

$ # first 10 lines
$ head foo.c
void f1 ( void **p ) {
    *p = 0;
}

void f2 ( ) {
    int *p1;
    void *p2;
    f1( &p1 );
    f1( &p2 );
}

$ # a subset of lines
$ sed -n '7,9p' foo.c
    void *p2;
    f1( &p1 );
    f1( &p2 );

regards,
George
