Removing substring from a string
Hi. I want to remove a substring from a string. If I use the "tr" command, it doesn't seem to to what I want it to:
echo './somestring.dat' | tr -d './'
results in
somestringdat
I want it to remove only occurances of the string './', rather than the individual character. The result should be: somestring.dat
How do I do this?
Thanks,
- Dylan

wcsstr(3) Library Functions Manual wcsstr(3)
NAME
wcsstr - Finds a wide-character substring
LIBRARY
Standard C Library (libc)
SYNOPSIS
#include <wchar.h>
wchar_t *wcsstr( const wchar_t *s1, const wchar_t *s2);
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
wcsstr(): XSH5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Specifies the wide-character string being searched. Specifies the wide-character substring to be located.
DESCRIPTION
The wcsstr() function locates the first occurrence in the wide-character string pointed to by the s1 parameter of the sequence of wide
characters in the wide-character string pointed to by the s2 parameter, excluding the terminating null wide character.
RETURN VALUES
Upon successful completion, the wcsstr() function returns a pointer to the located wide-character substring or a null pointer when the sub-
string is not found. If the s2 parameter points to a wide-character substring having 0 (zero) length, the wcsstr() function returns the
entire wide-character string pointed to by parameter s1.
[Tru64 UNIX] On error, the function returns a null pointer.
