Hi all, this is driving me nuts.
I need to evaluate if a variable in a shell script has a heading s or m character e.g. s92342394 or m9233489 if so then I need to get rid of them. I'm quite familiar with PERL and could do it there in 3 mins but I have not found a decent way to do this in a shell.... (1 Reply)
Googling the answer to this question just doesn't work when Google won't search your symbols for you. Can someone tell me what this command will assign to var2, and where I can find more information about using braces in this way?
var2=${var1#??????????}
Thanks so much. (2 Replies)

re_exec
RE_COMP(3) Linux Programmer's Manual RE_COMP(3)NAME
re_comp, re_exec - BSD regex functions
SYNOPSIS
#define _REGEX_RE_COMP
#include <sys/types.h>
#include <regex.h>
char *re_comp(char *regex);
int re_exec(char *string);
DESCRIPTION
re_comp() is used to compile the null-terminated regular expression pointed to by regex. The compiled pattern occupies a static area, the
pattern buffer, which is overwritten by subsequent use of re_comp(). If regex is NULL, no operation is performed and the pattern buffer's
contents are not altered.
re_exec() is used to assess whether the null-terminated string pointed to by string matches the previously compiled regex.
RETURN VALUE
re_comp() returns NULL on successful compilation of regex otherwise it returns a pointer to an appropriate error message.
re_exec() returns 1 for a successful match, zero for failure.
CONFORMING TO
4.3BSD.
NOTES
These functions are obsolete; the functions documented in regcomp(3) should be used instead.
