Hi..

What is the command to check total disk usage for specific directory in MG/GB/Byte ?

As example i want to check disk usage for directory pproc ?

Please help me..

Thank you,
Baharin

Take a look at the man page for man du (POSIX).

And if you meant the /proc directory, the "size" of that won't tell you anything as it's just a virtual file system which acts as an interface to kernel data structures.

I have tried a few steps using du command, but i do not what is the real size.

nv2am:/acec/nv2am> du pproc/
128     pproc/files/parseRules
116     pproc/files/ddf
115728  pproc/files
48      pproc/data/test
0       pproc/data/output
0       pproc/data/error
68      pproc/data
139022  pproc/

nv2am:/acec/nv2am> du -s pproc/
139040  pproc/

nv2am:/acec/nv2am> du -b pproc/
128     pproc/files/parseRules
116     pproc/files/ddf
115728  pproc/files
48      pproc/data/test
0       pproc/data/output
0       pproc/data/error
68      pproc/data
139022  pproc/

nv2am:/acec/nv2am> du -k pproc/
64      pproc/files/parseRules
58      pproc/files/ddf
57864   pproc/files
24      pproc/data/test
0       pproc/data/output
0       pproc/data/error
34      pproc/data
69511   pproc/
