Cer- + tain commands are disabled if this switch is provided (see + USAGE). + + -i Start off in insert mode. + + -r Start off in regular expression search mode. + + -c Start off in case insensitive search mode. + + -R Switch on read only mode (note this mode cannot be toggled + whilst in xed ). + +USAGE + 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. + + Below the banner is the editting area, with the file offset and hex + listing on the left, and the ASCII on the right. + + xed operates within two modes when editting; hex and ASCII. Below are + the key commands valid in each mode. Note that all the editting, sav- + ing and undo keys are ignored in read-only mode. + + HEX MODE + + Cursors keys + Move around file + + h j k l + As above + + < , ^B Move back one page + + > . ^F Move forward one page + + s Save file (not valid in -x mode) + + TAB Switch to ASCII mode + + $ Move to the end of the file + + ^ Move to the beginning of the file + + + Jump to a specified address (Note this address defaults to dec- + imal, but an hex address can be entered by prefixing the number + with '0x', and an octal address by prefixing with '0') + + R Restore byte from last saved/initial version (not valid in -x + mode) + + q Q ^C Quit + + 1-9 a-f A-F + Enter Hex value + + ^A Switch between overtype/insert (not valid in -x mode) + + ^T Switch between normal/regular expression search mode + + ^K Switch between case sensitive/insensitive search mode + + BS DEL Cancel after first hex digit is entered + + x Delete character at cursor (not valid in -x mode) + + / Search. In regular expression mode this will treat the file as + a set of text lines, each line terminated with a newline or + NULL. + + 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. + + ^R Redraw screen + + ASCII MODE + + Cursor keys + Move around file + + ^H ^J ^K ^L + As above + + ^B Move back one page + + ^F Move forward one page + + TAB Switch to HEX mode + + ^A Switch between overtype/insert (not valid in -x mode) + + ^X Delete character at cursor (not valid in -x mode) + + ^R Redraw screen + + ^C Quit + +ENVIRONMENT + xed will process these environment variables if present + + XEDARG Allows default arguments to be definied in the environment.

This may result in your file + being accidentally editted and saved. + + o The display is half-inverted and sometimes corrupts on some HP- + UX systems. This is a bug in their curses implementation. + + + + xed(1) |
