what to show:
- -a all files including .hidden -c use ctime for timestamps
- -d directory, not contents -i inode number
- -k block sizes in kilobytes -p put a '/' after dir names
- -q unprintable chars as '?' -s size (in blocks)
- -u use access time for timestamps -A list all files but . and ..
- -H follow command line symlinks -L follow symlinks
- -R recursively list files in subdirs -F append /dir *exe @sym |FIFO
- -Z security context
+ -a all files including .hidden -b escape nongraphic chars
+ -c use ctime for timestamps -d directory, not contents
+ -i inode number -p put a '/' after dir names
+ -q unprintable chars as '?' -s storage used (1024 byte units)
+ -u use access time for timestamps -A list all files but . and ..
+ -H follow command line symlinks -L follow symlinks
+ -R recursively list in subdirs -F append /dir *exe @sym |FIFO

output formats:
- -1 list one file per line -C columns (sorted vertically)
- -g like -l but no owner -h human readable sizes
- -l long (show full details) -m comma separated
- -n like -l but numeric uid/gid -o like -l but no group
- -x columns (horizontal sort)
