UNIX for Dummies Questions & Answers

HI ,

I have a very small requirement here. I need to find a file say which ends with .gz in a folder. If i found this file then i need to echo" file found" and do a word count of the file and if not i need to echo file not found and exit from the loop. i have written this script but i am only getting INPUT FILE FOUND FOR even if i don't have the ".gz " file in the folder.

Can anyone help to see what is wrong in this script that i have written

The script is below:

##!/usr/bin/sh
FROM_DIR=/home/sandy; export FROM_DIR
cd $FROM_DIR
for filename in $FROM_DIR/*.gz
do
find . -name '$FROM_DIR/*.gz'
if [ "$?" -ne 0 ]
then
echo " INPUT FILE NOT FOUND FOR ......." >>
else
echo " INPUT FILE FOUND FOR ......." >>
fi
wc -l *.cc3
done
exit 0

Since I'm not very familiar with ksh, i did it in bash, the following works for me :
cat run.bash

Code:

#!/bin/bash

FROM_DIR=/home/sysgate/builds
cd $FROM_DIR
for filename in *.gz
do
find . -name '*.gz'
if [ "$?" -ne 0 ]
then
echo " INPUT FILE NOT FOUND FOR ......."
else
echo " INPUT FILE FOUND FOR ......."
fi
wc -l *.cc3
done
exit 0

result :
I guess you should remove the $FROM_DIR, thus the forward slash will be removed also, just "*.gz".

Unsure what you mean by doing a count, I am thinking you are wanting to put the file names found into a file called something.cc3.

Here's something that may help you... You could probably modify it for your needs.

FOUNDFILE=/u/data/gzfilesfound
rm ${FOUNDFILE}
for filename in `ls ${FROMDIR}/*.gz` #If over or around 1000 files will not work
do
echo "${FILENAME}" >> ${FOUNDFILE}
done

if [ -s ${FOUNDFILE} ]
then
COUNT=`cat ${FOUNDFILE} | wc -l | tr -d " "`
echo "There were ${COUNT} Files found"
else
echo "No files Found"
fi

Hi benefactr,

sorry......... it was not .gz and but .cc3..............i am trying word count of the file

what i trying do is trying to find the .cc3 file .....and if i find any i should do a word count of the file .......if not found then say find not found


Please let me know if the above script that u gave is good enough or any changes are required

bsandeep,
Your script will always find the files, as you are looping thru
existing files in the directory:

Code:

...
for filename in $FROM_DIR/*.gz
...

If you are checking for one specific file, there is no need for a loop.
One way to check if a file exists:

Code:

mFileName='YourFile'
if [ -f ${mFileName} ]; then
  echo 'File '${mFileName}' exists number records = '`wc -w ${mFileName}`
else
  echo 'File '${mFileName}' does not exist.'
fi

Also if you want a "word count", the option in the 'wc' command is '-w', not '-l'.

Thanks so much shell life
