Error Getting all file names in a folder.

Hi All,
I need help to create a shell script that does following:

- do ls -1 and let all file names in the current folder
- do wc for each file and if wc > 0 then send a mail.

I am new to unix and do not know how to get filename one by one in a loop, so that wc can be done. I have done rest of the things but just looping all files is left.

Please help!

can you try this:
ls -1 > flist
for f in `cat flist`
  x=`wc $f | cut -c1-8`
  if [ x -gt 0 ]
    echo "send mail"
    echo "do nothing"

this leads me to ask what is the better way to
extract the character column from a wc command,
instead of cut -c1-8... any idea, anyone ??

HTH....any comment is appreciated. thanks.

Quite not all, but your code gave me enough idea to implement this. Following is what I have done and its working great.

Thanks a lot for your help.

For your thinking about using cut, well I used awk as its easier and will give me complete field regardless of its size.

strPath=`echo "/app70s/d001/staging/Test/BadFiles/"$1`

for file in `ls -l $strPath | grep -v drwx | awk '{print $9}'`
   echo ":" $file
   intCount=`wc $strPath/$file | awk '{print $1}'`
   if [ $intCount != 0 ]
       echo $file " contains bad records. Rows are failing." | mailx -s "Session Failed";

a problem with what you have writen is if the file/dir in question is not rwx for the owner. ie drx-

i would try something to the effect of
case "$1" in
DIR=${2:?"bad or missing Directory"}
for filelist in `ls $DIR`;do
        filesize=`ls -l $DIR/$filelist|awk '{ print $5 }'`
        if [[ $filesize == 0 ]];then
                echo "$filelist is $filesize"|mailx -s "SUBJECT" user@host

        echo ""
        echo "Usage: for $0 [-d] /directory/to/search"
        echo ""

Totally agree. Actually my application is custom for my environment and so I did not bothered about finding any dir because BadFiles folder should not have any sub-folders.

But what you told me is totally acceptable and I'm sure going to implement this. Just in case if someone creates a folder in future!

Thanks a lot for your inputs.
