strace mi vyklopi toto:

execve("/root/bin/crypt", ["crypt"], [/* 24 vars */]) = 0
strace: exec: No such file or directory


Prikladam jeste zdrojovy text toho scriptu, ktery se mi ale nedari
zkompilovat. Vypadava mi to na tom cteni ze vstupu "cin" a zapisu na
vystup "cout".
Nemuze najit jejich definici a me se ji bohuzel najit taky nepovedlo.
Nevite nekdo v jaky by to melo byt knihovne?
Kompiluji s gcc a parametrem -lcrypt, jinak to vypadava i na volani ty
fce crypt.
Mam RH 7.1.

    cin >> in; // read STDIN
    out = crypt (in, (char*)salt); // encrypt the password
    cout << out; // write encrypted password to STDOUT
