Control characters are displayed as ^X ( the characters (with the high bit set) are printed as -x, where x is the character specified by the seven low order bits. -t Causes tabs to be printed as ^I and form feeds as ^L. This option is ignored if the -v option is not specified. -e Causes a ``$'' character to be printed at the end of each line (prior to the new-line). This option is ignored if the -v option is not set. ¸¸ÀÏ µð·ºÅ丮 À̸§¿¡ À̸§ Àüü¸¦ ³ÖÀ¸¸é µÈ´Ù. ¿¹¸¦ µé¾î cd ".. IBM-PC¿¡¼´Â ÀÌ·¯ÇÑ ¹®ÀÚ¸¦ Ä¡±â À§Çؼ ÀÚ¸¦ ´·¯¼ ASCII ¹øÈ£¿¡ ¸Â°Ô ³Ö¾îÁÖ¸é µÈ´Ù.

Control assignments control-character C Sets control-character to C, where control-character is erase, kill, intr (interrupt), quit, eof, eol, swtch (switch), start, stop or susp. start and stop are available as possible control char- acters for the control-character C assignment. If C is preceded by a caret (^) (escaped from the shell), then the value used is the corresponding con- trol character (for example, ^D is a interpreted as DELETE and ^- is interpreted as unde- fined). stty -a ¸í·ÉÀ» ÀÌ¿ëÇؼ sttyÀÇ ÇöÀç ¼³Á¤ÀÌ ¾î¶»°Ô µÇ¾î ÀÖ´ÂÁö ¾Ë¼ö ÀÖ´Ù. ±×¸®°í ¾î¶² °ÍÀÌ ¹®Á¦¸¦ ÀÏÀ¸Å°°í ÀÖ´ÂÁö ¾Ë ¼ö ÀÖ´Ù.
