My objective was to capture the files locate in a particular path into a file, this is what I did in my bash script.
# find out all available file
files=$(ls -1 ${SRC_PATH}/*.txt)
echo "${files}" > ${TEMP_FILE}
# convert the space between each file into newline
sed 's/ /\n/g' ${TEMP_FILE} > ${PARSE_FILE}
# loop through each file and check the file size is greater than zero
for file in `cat ${PARSE_FILE}`; do
file_size=`ls -lah ${file} | awk '{ print $5 }'`
if [ $file_size -ne 0 ]; then
echo $file >> "${NICE_FILE}"
fi
done
After a few round of review and unit testing on my code, I realize there is a problem where
sed command was unable to handle file name with space within it. After a few round of rework, finally I came out a so called "perfect" solution.
# find out all available file
files=$(ls -1 ${SRC_PATH}/*.txt)
echo "${files}" > ${TEMP_FILE}
# loop through each file and check the file size is greater than zero
while read file
do
if [ -s "${file}" ]
then
newfile=$(echo "${file}" | sed 's, ,\\ ,g')
echo "${newfile}" >> "${NICE_FILE}"
fi
done < ${TEMP_FILE}
No, this is not yet the perfect solution, I'm sure there is always a better one beyond this universe.
