Also, it might be more efficient NOT to store >800 lines of curl output in a variable to be echo-ed|grep-ed and wc-ed later.
I'd do it in one piped statement and store the count in a variable to be compared later.

hi, im trying to compare two variables in csh to put in an if statement, eg:
set a = $firstnum
set b = $secondnum
if ($a -ge $b) echo $a
But I get an error ("if: Expression syntax"). How can I make csh see my variables as integers?
thanks in advance! (5 Replies)

wcsxfrm
WCSXFRM(3) BSD Library Functions Manual WCSXFRM(3)
NAME
wcsxfrm -- transform a wide string under locale
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <wchar.h>
size_t
wcsxfrm(wchar_t * restrict dst, const wchar_t * restrict src, size_t n);
DESCRIPTION
The wcsxfrm() function transforms a null-terminated wide character string pointed to by src according to the current locale collation order
then copies the transformed string into dst. No more than n wide characters are copied into dst, including the terminating null character
added. If n is set to 0 (it helps to determine an actual size needed for transformation), dst is permitted to be a NULL pointer.
Comparing two strings using wcscmp() after wcsxfrm() is equivalent to comparing two original strings with wcscoll().
RETURN VALUES
Upon successful completion, wcsxfrm() returns the length of the transformed string not including the terminating null character. If this
value is n or more, the contents of dst are indeterminate.
SEE ALSO
setlocale(3), strxfrm(3), wcscmp(3), wcscoll(3)
STANDARDS
The wcsxfrm() function conforms to ISO/IEC 9899:1999 (``ISO C99'').
BUGS
The current implementation of wcsxfrm() only works in single-byte LC_CTYPE locales, and falls back to using wcsncpy() in locales with
extended character sets.
Comparing two strings using wcscmp() after wcsxfrm() is not always equivalent to comparison with wcscoll(); wcsxfrm() only stores information
about primary collation weights into dst, whereas wcscoll() compares characters using both primary and secondary weights.
