(This is Don's domain.)
I have come across an anomaly in sh and dash compared to bash.
It involves echoing a character set to a file in sh and dash compared to bash.
It is probably easier to show the code and results first.
Results using OSX 10.14.1, default bash terminal.
I thought that anything inside single quotes was raw ascii text and \n and some others would be saved as such.
'bash' shows it correctly but going posix does, (in this case), a newline character sent to the file.
Am I missing something or does posix not allow raw text when backslash is used on things like '\f', (which found the problem), '\t' etc...

Hi,
I've been trying to write a regex to use in egrep (in a shell script) that'll fetch the names of all the files that match a particular pattern. I expect to match the following line in a file:
Name = "abc"
The regex I'm using to match the same is:
egrep -l '(^) *= *" ** *"$' /PATH_TO_SEARCH... (6 Replies)

tk_getdash
Tk_GetDash(3) Tk Library Procedures Tk_GetDash(3)__________________________________________________________________________________________________________________________________________________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.
