While this confirms my confusion (missing better words here..), I learned some new things allthough most of it was known.
Asdide the fact that 'echo' is both, for some reason I always thought that /bin/echo was the echo used when calling echo, and thus not realized the builtin existed - or that they are different 'code'. How to distinguish between builtin and external util? (e.g. echo) - Unix & Linux Stack Exchange
That I most likley could rely on the bash builtin 'echo' for the use of SWARM.
But none of that sounded certain, so I then I followed a link of the 2nd post (46 up votes) about the standarized commands by PSIX and ended up here: echo
Now, when you go down to the 'Application Usage' section, you'll see this part:
Now my final question, which of these 2 examples would you recomend?
I have to ask this, because I lack the practical experience of actual daily usage on different systems.
Anyway, I'm going to try this out now.
Lets see which works better as expected.
At least I know now that it wasnt a waste of time preparing $ECHO to use printf, what a relieve!
i made a lot of processes. here is the code:
main()
{
printf("\nEnter K="); scanf("%d",&k);
printf("Enter L="); scanf("%d",&l);
printf("\nFather id=%d\n",getpid());
x=0;
makechild();
sleep(2);
return 1;
}
int makechild()
{
for(q=1;q<=k;q++)
{
if(f=fork())
