GETSEGBYNAME(3) Library Functions Manual GETSEGBYNAME(3)NAME
getsegbyname - get the segment command for the named segment
SYNOPSIS
#include <mach-o/getsect.h>
const struct segment_command *getsegbyname(const char *segname);
DESCRIPTION
This routine returns the segment_command structure for the named segment if it exists in the Mach-O (Mach object) executable getsegby-
name(3) is linked into. Otherwise getsegbyname(3) returns NULL. It uses the link editor defined symbol _mh_execute_header and just looks
through the load commands. Since these are mapped into the __TEXT segment they are read-only and thus const by default.

GETSECTBYNAME(3) Library Functions Manual GETSECTBYNAME(3)NAME
getsectbyname, getsectdata - get the section information for the named section
SYNOPSIS
#include <mach-o/getsect.h>
const struct section *getsectbynamefromheader(
const struct mach_header *mhp,
const char *segname,
const char *sectname)
const struct section *getsectbyname(
const char *segname,
const char *sectname)
char *getsectdatafromheader(
const struct mach_header *mhp,
const char *segname,
const char *sectname,
unsigned long *size)
char *getsectdata(
const char *segname,
const char *sectname,
unsigned long *size)
char *getsectdatafromFramework(
const char *FrameworkName,
const char *segname,
const char *sectname,
unsigned long *size)
DESCRIPTION
Getsectbynamefromheader returns the section structure for the named section in the named segment if it exists in the specified Mach header
otherwise it returns NULL. If the specified Mach header comes from a dynamic library as returned by _dyld_get_image_header(3) the addr
field in the section structure will have to have _dyld_get_image_vmaddr_slide(3) added to it to make it a valid pointer.
Getsectbyname is the same as getsectbynamefromheader with its first argument being the link editor defined symbol _mh_execute_header.
Getsectdatafromheader returns the address to the data for the named section in the named segment if it exists in the specified Mach header.
Also it returns the size of the section data indirectly through the pointer size. Otherwise it returns NULL for the pointer and zero for
the size. If the specified Mach header comes from a dynamic library as returned by _dyld_get_image_header(3) the address to the data
returned will have to have _dyld_get_image_vmaddr_slide(3) added to it to make it a valid pointer.
Getsectdata is the same as getsectdatafromheader with its first argument being the link editor defined symbol _mh_execute_header.
getsectdatafromFramework is used to get the named section data from the named Framework. For example, the framework name ``Appkit'' would
be used for /System/Library/Frameworks/Appkit.framework/Versions/C/Appkit. If that Framework isn't being used by the program then it
returns NULL for the pointer and zero for the size.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:
12FX009:5 dpontius$ ls
ââWord FinderÂŽ Plusâ˘
12FX009:5 dpontius$ rm... (29 Replies)
