sed: letztes Wort einer Zeile

[Patrick Piecha]

Wie kann ich mit sed nur das letzte Wort einer Zeile ausgeben
lassen?

sed -e 's/.*[ \t]//'

Das tut bei mir irgendwie nicht, damit wird anscheinend _alles_
geloescht, ich bekomme nur Leerzeilen.

Wenn du besondere Tests willst (leere Zeilen nicht ausgeben
usw.) dann wird es komplizierter.

Nein, ich will einfach alles vor dem letzten Leerzeichen
wegschneiden. Mein Tool der Wahl waere ja cut, aber das kann
nur vorwaerts zaehlen und kennt keine "negativen" Spalten.

Achtung: das \t ist symbolisch gemeint, ist nicht
standardkonform und funktioniert auch nur mit neuen
GNU-sed-Varianten.

Das ist ein Minuspunkt, aber es kommen nur Leerzeichen vor.

Also es geht darum, aus C-Prototypen den Funktionsnamen zu
extrahieren.

Aus

static char* foo ( int bar ) ...

soll einfach nur "foo" werden, dazu schneide ich bereits mit cut
vor der oeffnenden Klammer.

PS: die richtige Gruppe zu dieser Frage ist de.comp.os.unix.shell

Oh. Stimmt.

Da würde ich (erst mal ohne "sed") etwa so vorgehen

rev $Zeile | cut -d" " -f1 | rev

Mag auch eleganter gehen, aber diese Lösung halte ich für
überschaubar.

Viele Grüße!

Hmmm. Stimmt, bei Solaris scheint das nicht vorhanden zu sein. Vergiß
also meinen Tipp in meinem anderen Posting.

Sollte auch so gehen:

sed 's/.*\<//g'

Das sieht mir brauchbar aus, danke.

Wenn du unbedingt mit cut arbeiten möchtest :)

Dann hast Du noch Leerzeichen nach dem letzten Wort.

D.h., es bleibt "static char* foo " übrig? Da ist das Leerzeichen schon.

Wie wär's, wenn Du das cut weglässt, und gleich mit

sed -e 's/.*[^A-Za-z0-9_]\([A-Za-z0-9_][A-Za-z0-9_]*\) *(.*)/\1/'

das letzte Wort vor den Klammern raussuchst?

Das funktioniert dann auch bei

static char *foo(bar)

Eine Schreibweise, die ich bei C bevorzugen würde (ich weiß, die
C++-Leute sehen das anders).

Deine Schreibweise im Stil von K&R ergibt als Prototyp wenig Sinn.
Interessant ist allerdings, dass gcc der Unfug nur eine Warnung
entlockt.

$ nl -ba a.c
1 char *foo(bar);
2 int main() { foo(27); return 0; }

$ gcc -c -Wall -ansi -pedantic a.c
a.c:1: warning: parameter names (without types) in function declaration

$ gcc -c -Wall -std=c99 -pedantic a.c
a.c:1: warning: parameter names (without types) in function declaration

C++ zeigt hier ein sinnvolleres Verhalten.

$ g++ -c -Wall -pedantic a.c
a.c:1: `bar' was not declared in this scope
a.c: In function `int main()':
a.c:2: `foo' cannot be used as a function

Sorry, sollte natürlich
static char *foo(int bar)
heißen. Was mich gestört hat waren die Spaces rund um "foo". (Der Inhalt
der Klammern ist für die Aufgabenstellung ohnehin irrelevant)

Das ist in der Tat interessant, denn soweit ich der in ANSI X3.159-1999
abgedruckten Grammatik entnehmen kann, ist das schlicht und ergreifend
ein Syntaxfehler.

Verwechselst Du da nicht Sprache und Compiler? Das sollte wohl heißen
"g++ zeigt hier ein sinnvolleres Verhalten".

Und keine Lösung (auch nicht meine mit awk) funktioniert,
wenn sowas dasteht:

stat char* foo
(
int bar, /* bar parameter */
char xyz /* zweiter parameter */
)

Patrick wird, um alle Fälle abdecken zu können, nicht umhin
kommen, einen echten C-Parser zu bemühen. cproto z.B.
enthält einen. Vielleicht sollte er mal sagen, was sein
Skript machen soll. Ich könnte mir denken, das es dafür
schon eine fertige Lösung gibt.

Tschau

Wie wäre es mit ctags oder etags? Das übernimmt das Parsen von C, und
der Output dürfte leicht weiter zu verarbeiten sein.

Noe, das ist hier Overkill.

Es existiert ein Script, das einen grossen Haufen C-Code
durchgrept und fuer jede Funktion den entsprechenden Prototypen
erzeugt und daraus ein vollstaendiges Headerfile baut.

Nun will ich ein .def-File fuer <duck> Visual C++ bauen, dazu
brauche ich den Funktionsnamen fuer die zu exportierenden
Symbole.

Mittlerweile laeuft das auch prima (mit der Angabe von Dietrich
Schaffer).

Also selbergebaut und nicht cproto?

Nun will ich ein .def-File fuer <duck> Visual C++ bauen, dazu
brauche ich den Funktionsnamen fuer die zu exportierenden
Symbole.

Was steht denn in so einem .def-File drin?

Im Prinzip die Namen der zu exportierenden Symbole. Man kann
sich natuerlich auch den gesamten Code mit cdecl und aehnlichem
Bledsinn zukippen, aber _ich_ will das nicht ...

sed -e 's/.*[ \t]//'

Das tut bei mir irgendwie nicht, damit wird anscheinend _alles_
geloescht, ich bekomme nur Leerzeilen.

Dann hast Du noch Leerzeichen nach dem letzten Wort.

Das Stoert nicht allzu doll, ausserdem bekomme ich das dann nun
wirklich einfach weg.

Also es geht darum, aus C-Prototypen den Funktionsnamen zu
extrahieren.
static char* foo ( int bar ) ...

D.h., es bleibt "static char* foo " übrig? Da ist das
Leerzeichen schon.
Wie wär's, wenn Du das cut weglässt, und gleich mit
sed -e 's/.*[^A-Za-z0-9_]\([A-Za-z0-9_][A-Za-z0-9_]*\) *(.*)/\1/'
das letzte Wort vor den Klammern raussuchst?

Hm, schaden kann's nicht ...

Post by Peter J. Holzer
Das funktioniert dann auch bei
static char *foo(bar)
Eine Schreibweise, die ich bei C bevorzugen würde (ich weiß,
die C++-Leute sehen das anders).

Die Deklarationen haben bei mir immer ein Leerzeichen vor dem
Namen:

static char* foo (bar)

Nein, ich will einfach alles vor dem letzten Leerzeichen
wegschneiden. Mein Tool der Wahl waere ja cut, aber das kann
nur vorwaerts zaehlen und kennt keine "negativen" Spalten.

Nimm awk:
awk '{print $NF}'

Tschau
