用Python时候没有TAB补全,挺痛苦的,以下是添加方法
1.准备一个Python脚本 cat > tab.py <<EOF
#!/usr/local/bin/python# python tab file import sysimport readlineimport rlcompleterimport atexitimport os# tab completionreadline.parse_and_bind('tab: complete')# history filehistfile = os.path.join(os.environ['HOME'], '.pythonhistory')try: readline.read_history_file(histfile)except IOError: passatexit.register(readline.write_history_file, histfile) del os, histfile, readline, rlcompleter EOF2.查看Python默认的模块存放位置[root@victor python2.7]# pythonPython 2.7.6 (default, Sep 17 2017, 04:41:33) [GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> import sys>>> sys.path['', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/site-packages']3.拷贝到目录下cp tab.py /usr/local/lib/python2.74.现在可以用了[root@victor python]# cp tab.py /usr/local/lib/python2.7[root@victor python]# pythonPython 2.7.6 (default, Sep 17 2017, 04:41:33) [GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> import tab>>> import sys>>> sys.sys.__class__( sys.__sizeof__( sys.displayhook( sys.getprofile( sys.ps1sys.__delattr__( sys.__stderr__ sys.dont_write_bytecode sys.getrecursionlimit( sys.ps2sys.__dict__ sys.__stdin__ sys.exc_clear( sys.getrefcount( sys.py3kwarningsys.__displayhook__( sys.__stdout__ sys.exc_info( sys.getsizeof( sys.setcheckinterval(sys.__doc__ sys.__str__( sys.exc_type sys.gettrace( sys.setdlopenflags(sys.__excepthook__( sys.__subclasshook__( sys.excepthook( sys.hexversion sys.setprofile(sys.__format__( sys._clear_type_cache( sys.exec_prefix sys.long_info sys.setrecursionlimit(sys.__getattribute__( sys._current_frames( sys.executable sys.maxint sys.settrace(sys.__hash__( sys._getframe( sys.exit( sys.maxsize sys.stderrsys.__init__( sys._mercurial sys.exitfunc( sys.maxunicode sys.stdinsys.__name__ sys.api_version sys.flags sys.meta_path sys.stdoutsys.__new__( sys.argv sys.float_info sys.modules sys.subversionsys.__package__ sys.builtin_module_names sys.float_repr_style sys.path sys.versionsys.__reduce__( sys.byteorder sys.getcheckinterval( sys.path_hooks sys.version_infosys.__reduce_ex__( sys.call_tracing( sys.getdefaultencoding( sys.path_importer_cache sys.warnoptionssys.__repr__( sys.callstats( sys.getdlopenflags( sys.platform sys.__setattr__( sys.copyright sys.getfilesystemencoding( sys.prefix
