Trimming spaces from a variable
Hi guys,
when I take substring of a particular data using this command
var=substr($0,11,10)
it comes with spaces, when I am trying to trim the spaces it is not allowing me to do that.
Can you please help me out on that.
As I have to reverse the output of the variable also.

a=substr($0,11,10)
a1=`echo "${a}" | sed 's/ *$//'`
then it give me this error
The error context is
>>> a1=` <<<

General guidelines
A pretty safe rule of thumb is: look at what has already been done and try to do the same.
o Tabulations should be avoided and replaced with eight spaces.
o Indentation is generally 4 spaces.
o Lines should wrap at most at 79 characters.
o Do not leave whitespace at the end of lines.
o Do not use multiple spaces for anything else than indentation.
o Code qui fait des warnings == code de porc == deux baffes dans ta gueule
C coding style
Try to use short names whenever possible (i for indices, w for width, cv for canvas...). Macros are always uppercase, variable and function
names are always lowercase. Use the underscore to separate words within names:
#define BROKEN 0
#define MAX(x, y) ((x > y) ? (x) : (y))
unsigned int x, y, w, h;
char *font_name;
void frobulate_every_three_seconds(void);
const is a suffix. It's char const *foo, not const char *foo.
Use spaces after commas and between operators. Do not use spaces after an opening parenthesis or before a closing one:
a += 2;
b = (a * (c + d));
x = min(x1, x2, x3);
Do not put a space between functions and the corresponding opening parenthesis:
int function(int);
A space can be inserted after keywords such as for, while or if, but consistency with the rest of the page is encouraged:
if(a == b)
return;
if (p == NULL)
Do not put parentheses around return values:
return a + (b & x) + d[10];
Opening braces should be on a line of their own, aligned with the current block. Braces are optional for one-liners:
int function(int a)
{
if(a & 0x84)
return a;
if(a < 0)
{
return -a;
}
else
{
a /= 2;
switch(a)
{
case 0:
case 1:
return -1;
break;
default:
return a;
}
}
}
