How to print tree layout in Sun?

Hello.

If you are looking for a command similar to "tree" in DOS/Windows: I do not know if there is an equivalent but I wrote a program to do this myself. The output is not very good yet.

#include <stdio.h>

#include <string.h>

#include <sys/types.h>

#include <sys/stat.h>

#include <dirent.h>

void printtree(char *dname,int lvl,dev_t dev)

{

struct stat st;

struct dirent *dnt;

static char buf[500];

DIR *d;

int i,l,m;

l=strlen(dname);

if(!dev)

{

stat(dname,&st);

dev=st.st_dev;

}

d=opendir(dname);

if(!d) return;

dname[ l ]='/';

while((dnt=readdir(d))!=NULL)

if(strcmp(dnt->d_name,".") && strcmp(dnt->d_name,".."))

{

m=0;

strcpy(dname+l+1,dnt->d_name);

lstat(dname,&st);

if(S_ISLNK(st.st_mode))

{

stat(dname,&st);

if(S_ISDIR(st.st_mode)) m=1;

}

else if(S_ISDIR(st.st_mode)) m=2;

if(m)

{

for(i=0;i<lvl;i++) printf("|");

printf("+ %s",dnt->d_name);

if(m==1)

{

i=readlink(dname,buf,sizeof(buf)-1);

if(i<0) printf(" <unknown symlink>");

else

{

buf[ i ]=0;

printf(" <symlink to %s>\n",buf);

}

}

else if(st.st_dev!=dev)

printf(" <mount point>\n");

else

{

printf("\n");

printtree(dname,lvl+1,dev);

}

}

}

closedir(d);

dname[ l ]=0;

}

main(int argc,char **argv)

{

static char a[500];

strcpy(a,(argc>1)?(argv[1]):".");

printtree(a,0,0);

return 0;

}

I hope this helps.
