Hi,

I have file name as Example

extract_ces_v3_p044444rlt_20160514045705.txt.pgp
extract_ces_v3_p044444rlt_20160614049705.txt.pgp
extract_ces_v3_p044444rlt_20160714046705.txt.pgp

I have to read file name based on date(i.e) files with same date and copy to another directory in shell script.

Thanks,
Caba.

  • What output/errors do you get?
  • What OS and version are you using?

Most importantly, What have you tried so far?

i tried to extract the date using the below code but not able to,can you please check

#Script for copying files from src to dest based on same date and time
#!/bin/bash

#Script Variables
SPATH="/remote/home/folder1"
DPATH="/remote/home/folder2"
SUFFIX_ARG="*.txt"
ACTION_TIME=`date +'%Y%m%d' "%H:%M:%S:"`


echo "${ACTION_TIME} Starting copy task" 
find ${SPATH} -type f -name "${SUFFIX_ARG}" -print | while read path
do
   FN="${path##*/}" #extract the file name from the path
   temp=${FN#*_} 
  date=${temp%.txt.pgp} # trying to get the date alone 
   echo "this is the file name"$FN 
   ACTION_TIME=`date +"%Y%m%d %T"`
     if [ -e "${DPATH}/${FN}" ]   #if the destination file exists, skip it
   then
      echo "${ACTION_TIME} Skipped: File ${DPATH}/${FN} already exist"  
   else
      
	   cp "$path" "${DPATH}/${FN} ${ACTION_TIME}"  
	   ACTION_TIME=`date +"['%y%m%d' %T]:"`
	   echo "${ACTION_TIME} Copy ${FN} to ${DPATH} Complete"  
   fi
   echo "done copy"
done

Some comments (not necessarily in severity order or order of appearance):

  • consider refraining from using variables named close to PATH (essential system variable for your session; used to locate commands!) so you don't mess up your session by accident.
  • your first ACTION_TIME assignment has a syntax error in the date command.
  • giving variables ( date ) identical names to commands may lead to confusion.
  • what do you create the date variable for in the first place?
  • consider using the recommended $(...) notation in lieu of the deprecated `...` for "command substitution".
  • your find command won't find any of the files quoted in post#1 as the pattern in SUFFIX_ARG doesn't match.
  • the test for existence is for a different file than the one actually copied, so probably pointless.

On top, the specification in post#1 is sparse by itself, and it is not improved by your second post. Why don't you take a step back, start over, and present your problem in a decent, precise, detailed way supported by samples?
