Question Creating table in Unix
Hi All,
In a given directory, I need to list the files present in it in the below given format as a table.

 
File name Permission Number of Bytes File Type
Telecom1 --w-r-x 1230 Directory
Telecom2 ---x---x---x 450 Device file
Telecom3 ------------ 4000 Hidden file

In the above example we have 3 files in a given directory Telecom 1,2,3. 1 is a Directory 2 is a Device file and 3 is a hidden file.

Thanks

You can use awk to rearange the fields from an ls command and add some logic to determine the type of file.

For example:
Code:
ls -al | awk '
  /^total/ { next }
  {
    TYPE = "regular file"
    if ($1 ~ /^d/)
      TYPE = "directory"
    else if ($NF ~ /^\./)
      TYPE = "hidden file"
    else if ($1 ~ /^b/)
      TYPE = "block device"
    else if ($1 ~ /^p/)
      TYPE = "pipe"
 
    printf( "%-30s %14s %10d %s\n",  $NF, $1, $5, TYPE)
  }
'
.                                  drwxr-xr-x       4096 directory
..                                 drwxr-xr-x       4096 directory
file1                              -rw-r--r--        141 regular file
file2                              -rw-r--r--         30 regular file
my_logfile                         -rw-r--r--          6 regular file
myPipe                             prw-r--r--          0 pipe
T                                  -rwx------        185 regular file
tmp                                drwxr-xr-x       4096 directory
tmp2                               drwxr-xr-x       4096 directory
.x                                 -rw-r--r--          0 hidden file
Y                                  -rwx------        321 regular file

Which OS / Shell are you using? It's not clear from your permission fields how you determine what's what. (i.e. a file with ---------- does not respresent a hidden file)

Hi scottn,
Thanks for the reply, the file is a hidden file starts with "." with file permission mode "000". Thats why it's showing like that.

Can we make it look like a table with the column heading as given below
File name Permission Number of Bytes File Type

The output of scottns programm is controlled only by the last line "printf(....". Just change the output format to your needs and you are done (see "man printf" for details, awks printf works exactly the same way as the C function).

I hope this helps.
