I have a yet another variation, called `stat'. It is like
ls(1) except you specify what stat fields you want using a
printf style format string. I added -n flag to print out
numeric values instead of symbolic ones where it makes sense.
I originally wrote it many years ago because access to stat
fields from shell scripts is such a pain. Yours for asking.
$ stat -h
Usage: stat [-a | -f format] [-h] [-n] [-L] files...
where options are:
-a print all attributes
-f format print using a printf like format
-h this help message
-L follow symbolic links
-n prints numeric values not symbolic values
The -f format is as follows:
\ escapes are as in printf
any other non % char is printed as is, %% prints a single %
a stat field is printed using %[-][width][.width]<letter> format.
- for left justification, width[.width] is as for %s format of printf
<letter> can be one of:
a file access time
b allocated blocks
c inode change time
d dev
f flags
g group
G generation
l links
m file modify time
n file name
p permissions: r=read w=write x=exec S=suid/sgid s=suid/sgid+x
T=sticky t=sticky+x
r raw dev
s size
t type: b=block c=char d=dir -=file p=fifo s=socket l=symlink w=whiteout
u user
The default format is "%t%p %2l %-6u %-6g %9s %m %n\n"
Format for the -a option is "%a|%b|%c|%d|%f|%g|%G|%i|%l|%m|%p|%r|%s|%t|%u|%n\n"
