Bash script to find the number of files and identify which ones are 0 bytes.
I am writing a bash script to find out all the files in a directory which are empty. I am running into multiple issues. I will really appreciate if someone can please help me.
Code:
#!/bin/bash
DATE=$(date +%m%d%y)
TIME=$(date +%H%M)
DIR="/home/statsetl/input/civil/test"
Logfile="$DIR/log/log_filesize_$DATE_$TIME.log"
d=0
f=0
#i=1
count="'ls C.RA.VCCXXXX.* -1|wc -l'"
echo "$count"
until [$count -lt 1 ];
do
for filename in '-s $DIR/C.RA.VCCXXXX.*'
do
if [ -s "$filename" ] ; then
let d=d+1
#d++;
else
let f=f+1
mail -s 'Empty File' xxxxx@xxxxxx.com
#f++;
fi
done
let count=count-1
done
echo $d" files have greater than zero length"
echo $f" files have zero length"

I'm looking to create a Korn Shell script that, if given a directory as an arg, will calc bytes used by all files in the given directory and display that info. If no command line arg is given the program is to calc and display the bytes used by all the files in the pwd.

tping
TPING(1) LAM COMMANDS TPING(1)NAME
tping - Send echo messages to LAM nodes.
SYNOPSIS
tping [-hv] [-c count] [-d delay] [-l length] nodes
OPTIONS -h Print the command help menu.
-v Turn OFF verbose mode.
-c count Send count messages.
-d delay Delay delay seconds between each message.
-l length Each message is length bytes long.
DESCRIPTION
The tping command sends messages to, and collects replies from, a list of nodes, via the LAM echo server. It is similar to the UNIX
ping(8) command, and is used as a quick diagnosis of the LAM network.
Unless options are specified, tping sends a 1 byte message an infinite number of times, displaying the roundtrip time of each message as it
completes, with a delay of 1 second between roundtrips. After the loop is broken (with keyboard interrupt, eg: ^C), tping prints statis-
tics about all roundtrip messages.
EXAMPLES
tping h
Echo messages to the local node.
tping -v n7 -l 1000 -c 10
Echo 1000 byte messages to node 7. Stay silent while working. Stop after 10 roundtrips and report statistics.
BUGS
There is no built-in timeout and tping will wait forever to receive an echo. If no echo is received, due to a dead link or node, tping
hangs. Stop the process with a keyboard suspend signal (eg: ^Z) and terminate LAM with lamhalt(1) or lamwipe(1) (although the use of
lamwipe(1) is deprecated).
