all files-search and delete
I have n number of files like
Code:
custpoten_123.txt
custpoten_456.txt
custpoten_789.txt
custpoten_765.txt

from above all files i want to serach for a particular number and it should delete the whole line.i have a code for search and delete.
code is
Code:
#!/usr/bin/sh
srcfile=/ushhquest/data001/SrcFiles/viv.txt
tgtfile=/ushhquest/data001/SrcFiles/output.txt
awk -F, '$6 == 5 {next}1' $srcfile > $tgtfile
rm -f $srcfile
mv $tgtfile $srcfile
echo "completed"

now above code can search only for one file,i want to search and delete for all above files starting with name custpoten_*.txt in the particular folder.

Can anyone plz tell the code for search and delete all the files in a folder.

This was not checked in command line, so try it first, before you use it.

Code:
#!/usr/bin/sh
MY_PATH="/ushhquest/data001/SrcFiles/"
MY_TMP=`mktmp`

for srcfile in ${MY_PATH}/*.txt ; do 
awk -F, '$6 == 5 {next}1' ${srcfile} > $TMP_FILE
cat $TMP_FILE > $srcfile
echo -n "."
done

rm -f ${TMP_FILE}
echo -e "***\tDONE\t***"

Bug Just add one while loop.
Code:
ls  custpoten_*.txt  > sample_txt_files

while read line
do
  srcfile="/ushhquest/data001/SrcFiles/"$line
  tgtfile=/ushhquest/data001/SrcFiles/output.txt
  awk -F, '$6 == 5 {next}1' $srcfile >> $tgtfile
  rm -f $srcfile
  mv $tgtfile $srcfile
done<sample_txt_files
echo "completed"

why we are using my_tmp in the script,moreover folder may contain the files which is not starting with custpoten.

ls custpoten_*.txt > sample_txt_files ## this will create one list of your required .txt files.

and $line indicates .txt file name.

In while loop we operate on one file at one time.

Let me know if u still have more doubt ?

This is a useless use of ls *, where the ls technically serves no function at all -- it finds no files, it's only used to repeat input the shell has already found ( *, etc, are processed in the shell, not in ls ).

You can use the shell builtin printf instead:
Code:
printf "%s\n" custpoten_*.txt > sample_txt_files
