It effectively invokes 53.Xr lpr 1 54with the proper set of arguments. 55 56It generally prints the named files on the destination printer. 57.Pp 58Option 59.Fl c 60makes the 61.Nm 62command exit only after further access to any of the input files is no 63longer required. The application can then safely delete or modify the 64files without affecting the output operation. 65 66To specify a particular printer, option 67.Fl d Ar dest 68can be used. If no 69.Fl d 70is provided on the command line, the contents of the environmental 71variables 72.Ev LPDEST 73or 74.Ev PRINTER 75.Pq with this precedence 76are taken as the destination printer. 77 78Option 79.Fl n Ar num 80can be used to specify that 81.Ar num 82copies of each of the named files shall be printed. 83 84.Sh ENVIRONMENT 85As described above, the variables 86.Ev LPDEST 87and 88.Ev PRINTER 89are examined to select the destination printer. 90 91.Sh SEE ALSO 92.Xr lpr 1 93.Sh STANDARDS 94The 95.Nm lp 96command is expected to comply with the 97.St -p1003.2 98specification. 99.Sh AUTHOR 100This implementation of the 101.Nm 102command has been written by 103.if t J\(:org Wunsch. 104.if n Joerg Wunsch. 105.Sh BUGS 106The 107.St -p1003.2 108specification does not provide any means to print non-text files. It 109rather requires the files to be printed to be text files limited to 110reasonable line lengths and printable characters. 111
