DU(1) DU(1) NAME du - disk usage SYNOPSIS du [ -a ] [ -f ] [ -n ] [ -t ] [ -u ] [ -bsize ] [ file ... ] DESCRIPTION Du gives the number of Kbytes allocated to data blocks of named files and, recursively, of files in named directories. It assumes storage is quantized in units of 1024 bytes (Kbytes) by default. Other values can be set by the -b option; size is the number of bytes, optionally suffixed k to specify multiplication by 1024. If file is missing, the current directory is used. The count for a directory includes the counts of the contained files and directories. The -a option prints the number of blocks for every file in a directory. Normally counts are printed only for contained directories. The -f option ignores errors, otherwise it stops on the first error. The -n option prints the size in bytes and the name of each file; it sets -a. The -t option prints, in the format of du -n, the modified time of each file rather than the size. If the options -tu are specified then the accessed time is printed. SOURCE /sys/src/cmd/du.c Page 1 Plan 9 (printed 12/27/24)
