Usage: ar [emulation options] [-]\{dmpqrstx}[abcDfilMNoOPsSTuvV] [--plugin <name>] [member-name] [count] archive-file file...
 ar -M [<mri-script]
 commands:
 d - delete file(s) from the archive
 m[ab] - move file(s) in the archive
 p - print file(s) found in the archive
 q[f] - quick append file(s) to the archive
 r[ab][f][u] - replace existing or insert new file(s) into the archive
 s - act as ranlib
 t[O][v] - display contents of the archive
 x[o] - extract file(s) from the archive
 command specific modifiers:
 [a] - put file(s) after [member-name]
 [b] - put file(s) before [member-name] (same as [i])
 [D] - use zero for timestamps and uids/gids (default)
 [U] - use actual timestamps and uids/gids
 [N] - use instance [count] of name
 [f] - truncate inserted file names
 [P] - use full path names when matching
 [o] - preserve original dates
 [O] - display offsets of files in the archive
 [u] - only replace files that are newer than current archive contents
 generic modifiers:
 [c] - do not warn if the library had to be created
 [s] - create an archive index (cf. ranlib)
 [S] - do not build a symbol table
 [T] - make a thin archive
 [v] - be verbose
 [V] - display the version number
 @<file> - read options from <file>
 --target=BFDNAME - specify the target object format as BFDNAME
 --output=DIRNAME - specify the output directory for extraction operations
 optional:
 --plugin <p> - load the specified plugin
 emulation options: 
 No emulation specific options
