Certain commands are +disabled if this switch is provided (see USAGE). +.TP +.B \-i +Start off in insert mode. +.TP +.B \-r +Start off in regular expression search mode. +.TP +.B \-c +Start off in case insensitive search mode. +.TP +.B \-R +Switch on read only mode (note this mode cannot be toggled whilst in +.B xed +). +.SH USAGE +.B xed +is a simple hex and ASCII based file editor. The display is made up of a +banner, which describes the file being editted; the size of the file (in hex); +the cursor position within the file (in hex); whether you are operating in +overtype or insert mode; whether you are in simple string or regular +expression search mode and the case sensitivity of the search. +.LP +Below the banner is the editting area, with the file offset and hex listing on +the left, and the ASCII on the right. +.LP +.B xed +operates within two modes when editting; hex and ASCII. Below are +the key commands valid in each mode. Note that all the editting, saving and +undo keys are ignored in read-only mode. +.TP +HEX MODE +.TP +Cursors keys +Move around file +.TP +h j k l +As above +.TP +< , ^B +Move back one page +.TP +> . ^F +Move forward one page +.TP +s +Save file (not valid in \-x mode) +.TP +TAB +Switch to ASCII mode +.TP +$ +Move to the end of the file +.TP +^ +Move to the beginning of the file +.TP ++ +Jump to a specified address (Note this address defaults to decimal, but an hex +address can be entered by prefixing the number with '0x', and an octal address +by prefixing with '0') +.TP +R +Restore byte from last saved/initial version (not valid in \-x mode) +.TP +q Q ^C +Quit +.TP +1-9 a-f A-F +Enter Hex value +.TP +^A +Switch between overtype/insert (not valid in \-x mode) +.TP +^T +Switch between normal/regular expression search mode +.TP +^K +Switch between case sensitive/insensitive search mode +.TP +BS DEL +Cancel after first hex digit is entered +.TP +x +Delete character at cursor (not valid in \-x mode) +.TP +/ +Search. In regular expression mode this will treat the file as a set of +text lines, each line terminated with a newline or NULL. +.TP +n +Search next. Note that this will perform the last search, regardless of any +mode change to/from regular expression mode, though it will take account of +changes to case sensitivity. +.TP +^R +Redraw screen +.TP +ASCII MODE +.TP +Cursor keys +Move around file +.TP +^H ^J ^K ^L +As above +.TP +^B +Move back one page +.TP +^F +Move forward one page +.TP +TAB +Switch to HEX mode +.TP +^A +Switch between overtype/insert (not valid in \-x mode) +.TP +^X +Delete character at cursor (not valid in \-x mode) +.TP +^R +Redraw screen +.TP +^C +Quit +.SH ENVIRONMENT +xed will process these environment variables if present +.TP +XEDARG +Allows default arguments to be definied in the environment. If this is set +then invoking +.B xed +will be the same as invoking +.B xed $XEDARG <arglist> +.SH SEE ALSO +.BR od (1) +.BR grep (1) +.BR curses (3) +.BR regexp (3) +.SH DIAGNOSTICS +The diagnostics produced by +.B xed +are intended to be self-explanatory. +.SH NOTES +Version 2.0 of +.B xed +includes these additions and fixes over 1.7 : +.TP +o +Drastically tidied up code to enter the 1990's at least. +.SH BUGS +.TP +o +Even though the input routine tries it's best to mask them, pressing certain +control keys (function keys, etc) while +.B xed +is waiting for the second hex digit when editting can send a string of +unexpected commands to +.B xed. +This may result in your file being accidentally editted and saved. +.TP +o +The display is half-inverted and sometimes corrupts on some HP-UX systems. This +is a bug in their curses implementation. |
