erasing portion of line with sed (only once)
hi,
I'm trying to use sed to erase everything, up to the first parenthesis. for example:
input: blah blah blah (aldj) test (dafs) test test.
output: (aldj) test (dafs) test test.
how would i do this?
I was fooling around with the parenthesis, and i only got it to apply on all parenthesis. What would I need to do to make it work on the first parenthesis. Here's what I had:
sed "s|.*(||" filename > output
thanks,
gammaman

Hi,
This is more a theoretical question, because I usually solved that with perl or even java, but I would like to know if it exists an easy way to do it with SED.
Using regular expresions it's very easy to select an portion line. Does it exist an easy way for printing those portions in SED?... (1 Reply)

strtok_r
STRTOK(3) BSD Library Functions Manual STRTOK(3)
NAME
strtok, strtok_r -- string tokens
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>
char *
strtok(char *str, const char *sep);
char *
strtok_r(char *str, const char *sep, char **last);
DESCRIPTION
This interface is obsoleted by strsep(3).
The strtok() function is used to isolate sequential tokens in a null-terminated string, str. These tokens are separated in the string by at
least one of the characters in sep. The first time that strtok() is called, str should be specified; subsequent calls, wishing to obtain
further tokens from the same string, should pass a null pointer instead. The separator string, sep, must be supplied each time, and may
change between calls.
The implementation will behave as if no library function calls strtok().
The strtok_r() function is a reentrant version of strtok(). The context pointer last must be provided on each call. The strtok_r() function
may also be used to nest two parsing loops within one another, as long as separate context pointers are used.
The strtok() and strtok_r() functions return a pointer to the beginning of each subsequent token in the string, after replacing the token
itself with a NUL character. When no more tokens remain, a null pointer is returned.
EXAMPLES
The following uses strtok_r() to parse two strings using separate contexts:
char test[80], blah[80];
char *sep = "\/:;=-";
char *word, *phrase, *brkt, *brkb;
strcpy(test, "This;is.a:test:of=the/string\tokenizer-function.");
for (word = strtok_r(test, sep, &brkt);
word;
word = strtok_r(NULL, sep, &brkt))
{
strcpy(blah, "blah:blat:blab:blag");
for (phrase = strtok_r(blah, sep, &brkb);
phrase;
phrase = strtok_r(NULL, sep, &brkb))
{
printf("So far we're at %s:%s
", word, phrase);
}
}
SEE ALSO
memchr(3), strchr(3), strcspn(3), strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), wcstok(3)
STANDARDS
The strtok() function conforms to ISO/IEC 9899:1990 (``ISO C90'').

Based on the FreeBSD 3.0 implementation.
BUGS
The System V strtok(), if handed a string containing only delimiter characters, will not alter the next starting point, so that a call to
strtok() with a different (or empty) delimiter string may return a non-NULL value. Since this implementation always alters the next starting
point, such a sequence of calls would always return NULL.
