Renaming a file with sequence number
Hi team,

I need a script for renaming a file with sequence number. script get a file from one directory, /home/billing/Cmm/sms/sms_tmp, append sequence no at the end of file name and move a file to other directory, /home/billing/Cmm/sms/.

Actual file is cdr201508271527, and file after renaming cdr201508271527_00001. Script also have capability to save the state of sequence number so when next time it will increment it will start increment from the last file transferred. I have a multiple files in /home/billing/Cmm/sms/sms_tmp. Each file can be identify with time stamp.

Hello mfaizen40,

Following may help you in same, but I didn't test it as no system as of now with me.
Code:
ACTUAL_PATH=/home/billing/Cmm/sms
TMP_PATH=/home/billing/Cmm/sms/sms_tmp
SEQ_FILE=/home/billing/Cmm/sms/squence_file.txt
LIST_FILES=/home/billing/Cmm/sms/files_list
PREVIOUS_LIST=/home/billing/Cmm/sms/previous_file_list
FILES_NEEDS_TO_BE_CREATED=/home/billing/Cmm/sms/files_needs_to_be_created
find $TMP_PATH -type f -printf "%f\n" 2>/dev/null > $LIST_FILES
VAL=`cat $SEQ_FILE`
if [[ -s $PREVIOUS_LIST ]]
then
	awk 'FNR==NR{A[$0];next} !($0 in A){print $0}' $PREVIOUS_LIST $LIST_FILES > $FILES_NEEDS_TO_BE_CREATED
	while read line
	do
		let "VAL = VAL + 1"	
                VAL1=`printf "%05d\n" $VAL`	
                mv $TMP_PATH"/"$line $ACTUAL_PATH"/"$line"_"$VAL1
	done < "$FILES_NEEDS_TO_BE_CREATED"
else
	while read line
	do
		let "VAL = VAL + 1"
                VAL1=`printf "%05d\n" $VAL`	
                mv $TMP_PATH"/"$line $ACTUAL_PATH"/"$line"_"$VAL1
	done < "$PREVIOUS_LIST"
fi	
        

printf "%05d" $VAL1 > $SEQ_FILE
mv $LIST_FILES $PREVIOUS_LIST

You can save above code as a script and give that script as permission according to
your convince and try it out, hope this is helpful. Please do let us know how it goes for you.

Thanks,
R. Singh

Sounds like: Appending sequence number at the end of file name

Any attempts from your side?

Hello mfaizen40,

Just adding same above code with a use of function to reuse of code.
Hope this will be helpful.
Code:
ACTUAL_PATH=/home/billing/Cmm/sms
TMP_PATH=/home/billing/Cmm/sms/sms_tmp
SEQ_FILE=/home/billing/Cmm/sms/squence_file.txt
LIST_FILES=/home/billing/Cmm/sms/files_list
PREVIOUS_LIST=/home/billing/Cmm/sms/previous_file_list
FILES_NEEDS_TO_BE_CREATED=/home/billing/Cmm/sms/files_needs_to_be_created
find $TMP_PATH -type f -printf "%f\n" 2>/dev/null > $LIST_FILES
VAL=`cat $SEQ_FILE`
VAL1=`printf "%05d\n" $VAL`	

MAKE_CHECK_FILE() {
Input_file=$1
	while read line
	do
		let "VAL = VAL + 1"	
                VAL1=`printf "%05d\n" $VAL`	
                mv $TMP_PATH"/"$line $ACTUAL_PATH"/"$line"_"$VAL1
	done < "$Input_file"

	           }


if [[ -s $PREVIOUS_LIST ]]
then
	awk 'FNR==NR{A[$0];next} !($0 in A){print $0}' $PREVIOUS_LIST $LIST_FILES > $FILES_NEEDS_TO_BE_CREATED
        MAKE_CHECK_FILE $FILES_NEEDS_TO_BE_CREATED
else
        MAKE_CHECK_FILE $PREVIOUS_LIST
fi	
        

printf "%05d" $VAL1 > $SEQ_FILE
mv $LIST_FILES $PREVIOUS_LIST

Thanks,
R. Singh

Hello mfaizan40,

I have created a same directory structure in my /tmp and executed the following(previous script with minor change), it worked for me.
Code:
cat check_move_files.ksh
ACTUAL_PATH=/tmp/home/billing/Cmm/sms
TMP_PATH=/tmp/home/billing/Cmm/sms/sms_tmp
SEQ_FILE=/tmp/home/billing/Cmm/sms/squence_file.txt
LIST_FILES=/tmp/home/billing/Cmm/sms/files_list
PREVIOUS_LIST=/tmp/home/billing/Cmm/sms/previous_file_list
touch $SEQ_FILE $LIST_FILES
FILES_NEEDS_TO_BE_CREATED=/tmp/home/billing/Cmm/sms/files_needs_to_be_created
find $TMP_PATH -type f -printf "%f\n" 2>/dev/null > $LIST_FILES
VAL=`cat $SEQ_FILE`
VAL1=printf "%05d\n" $VAL
ONE=1
MAKE_CHECK_FILE() {
Input_file=$1
        while read line
        do
                VAL=`expr $VAL + $ONE`
                VAL1=`printf "%05d\n" $VAL`
                mv $TMP_PATH"/"$line $ACTUAL_PATH"/"$line"_"$VAL1
        done < $Input_file
                    }
 
if [[ -s $PREVIOUS_LIST ]]
then
        awk 'FNR==NR{sub(/\_.*/,X,$0);A[$0];next} !($0 in A){print $0}' $PREVIOUS_LIST $LIST_FILES > $FILES_NEEDS_TO_BE_CREATED
        MAKE_CHECK_FILE $FILES_NEEDS_TO_BE_CREATED
else
        MAKE_CHECK_FILE $LIST_FILES
fi
 
printf "%05d" $VAL1 > $SEQ_FILE
mv $LIST_FILES $PREVIOUS_LIST

Please remove /tmp from solution and try it, let me know if you have any queries. Please test all scenarios like first create some files and run it and then create some same name files and try to run script it shouldn't move already existing ones and move the new ones.

Thanks,
R. Singh

Hi RavinderSingh13...

Where has $VAL2, (line 19), come from?
Code:
                echo $VAL1 $VAL2

It will always be a NULL...
If I am wrong I stand corrected...
