- Command-u and Control-u now erase the current command line. This is done with a 'cut' operation, so the erased line can be retrieved with a paste.
- MacShell can now execute scripts which begin with the two characters '#!' as normal commands (without using 'source').
- Path and manpath shell variables now supported.
***Version 0.52b 1/3/95***
- Shell aliases are now supported.
- Scripts now receive arguments from the command line in the form of a special shell variable 'argv'.
- Fixed a bug which caused paste into the interactive window to ignore what was currently on the command line.
- The user may now set a special shell variable called "tabnc" to force the tab key to trigger the name completion mechanism.
- Modified man so that MacShell can load manual entries from external code resources.
- Echo now puts a newline after its output when called from a script.
- MacShell now correctly parses an argument which contains embedded quotes.
***Version 0.51b 11/9/94***
- Added features to allow the placeholder '{}' in the exec string of the find command to be replaced even if it doesn't form a separate argument, and to allow multiple place holders to be used in one exec string.
- Corrected a fatal oversight which caused the maximum number of arguments on a command line to be limited to 128 or 64. The maximum should now be 32k.
- Fixed a fatal bug in the name completion function which appeared when used in directories containing large numbers of files and directories.
- Pasting into an interactive window now causes the text to appear after the insertion point if the beginning of the selection range is before the end of the prompt. Otherwise it performs a normal paste.
- Cut now works on text after the current prompt.
- Backspace can no longer delete the space before the prompt if text follows the insertion point.
