| 9 | .SH NAME | |
| 10 | gets \- get a string from standard input | |
| 11 | .SH SYNOPSIS | |
| 12 | .B gets | |
| 13 | [ default ] | |
| 14 | .SH DESCRIPTION | |
| 15 | .B N.B.: | |
| 16 | This command was introduced for use in \fI.login\fR scripts when the facilities | |
| 17 | of the | |
| 18 | .IR tset (1) | |
| 19 | command were not totally adequate in setting the terminal type. | |
| 20 | This is no longer true, and | |
| 21 | .I gets | |
| 22 | should no longer be needed. | |
| 23 | To boot, a construct ``$<'' is available in | |
| 24 | .IR csh (1) | |
| 25 | now which has the functionality of | |
| 26 | .IR gets: | |
| 27 | .IP | |
| 28 | \fBset a=$<\fR | |
| 29 | .br | |
| 30 | \fBif ($a == '') set a=default | |
| 31 | .LP | |
| 32 | replaces | |
| 33 | .IP | |
| 34 | \fBset a=`gets default`\fR | |
| 35 | .LP | |
| 36 | Users of | |
| 37 | .IR sh (1) | |
| 38 | should use its | |
| 39 | .I read | |
| 40 | command rather than | |
| 41 | .I gets. | |
| 42 | .PP | |
| 43 | .I Gets | |
| 44 | can be used with | |
| 45 | .IR csh (1) | |
| 46 | to read a string from the standard input. | |
| 47 | If a | |
| 48 | .I default | |
| 49 | is given it is used if just return is typed, or if an error occurs. | |
| 50 | The resultant string (either the default or as read from the standard | |
| 51 | input is written to the standard output. | |
| 52 | If no | |
| 53 | .I default | |
| 54 | is given and an error occurs, | |
| 55 | .I gets | |
| 56 | exits with exit status 1. | |
| 57 | .SH "SEE ALSO" | |
| 58 | csh (1) | |
| 59 | .SH BUGS | |
| 60 | .I Gets | |
| 61 | is obsolete. |
