Top Forums Shell Programming and Scripting For x in a b c; { list; } (in lieu of do list; done) works (in bash) - why and how? Post 302766003 by Scrutinizer on Monday 4th of February 2013 03:47:24 AM

I think this undocumented syntax is still there for historical reasons and should not be used. I noticed it works in both old and new bash versions. It also works in zsh and ksh93, but not in ksh88. It is not POSIX compliant and does not work in dash.

NAME
Tk_GetDash - convert from string to valid dash structure. SYNOPSIS
#include <tk.h> int Tk_GetDash(interp, string, dashPtr) ARGUMENTS
Tcl_Interp *interp (in) Interpreter to use for error reporting. const char * string (in) Textual value to be converted. Tk_Dash *dashPtr (out) Points to place to store the dash pattern value converted from string. _________________________________________________________________ DESCRIPTION
These procedure parses the string and fills in the result in the Tk_Dash structure. The string can be a list of integers or a character string containing only ".,-_" or spaces. If all goes well, TCL_OK is returned. If string does not have the proper syntax then TCL_ERROR is returned, an error message is left in the interpreter's result, and nothing is stored at *dashPtr. The first possible syntax is a list of integers. Each element represents the number of pixels of a line segment. Only the odd segments are drawn using the "outline" color. The other segments are drawn transparent. The second possible syntax is a character list containing only 5 possible characters ".,-_ ". The space can be used to enlarge the space between other line elements, and can not occur as the first position in the string. Some examples: -dash . = -dash {2 4} -dash - = -dash {6 4} -dash -. = -dash {6 4 2 4} -dash -.. = -dash {6 4 2 4 2 4} -dash {. } = -dash {2 8} -dash , = -dash {4 4} The main difference of this syntax with the previous is that it is shape-conserving. This means that all values in the dash list will be multiplied by the line width before display. This assures that "." will always be displayed as a dot and "-" always as a dash regardless of the line width. On systems where only a limited set of dash patterns, the dash pattern will be displayed as the most close dash pattern that is available. For example, on Windows only the first 4 of the above examples are available. The last 2 examples will be displayed identically as the first one. KEYWORDS
