Case is very nice in every sh (sh, ksh, dash, bash, zsh, ...) to make string pattern
testing.
Why "$TBS" ? If TBS is empty, you get error if not "". Usually it's safety to use always " " with variable. String length 0 / null string.
Hi! I'm using
echo $string | grep "" -c
to test in a script if a string is a number and it seems to work. But how can i find, for example, if a string is a four figures number ?
Thanks to all! (2 Replies)

Anyways, here's my code:

I read a command on every loop an execute it.
I check if the string equals the word stop to end the loop,but it say that I gave too many arguments to test.
For example echo hello.

Hello all,
I'm trying to automate an if statement in my Perl script. The script opens an input file for reading, checks each line in the file for a particular substring, and if it finds the substring, writes it to an output file.
There are approximately 200 different input files. Each has... (3 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.
