Archiving a log file to a directory with the date incorporated in the new name

[J65nko]

Being tired of renaming my serial.log files, I hacked the following script.
I left in the comments and the debugging stuff, so you can see my step by step approach

#!/bin/sh

FILE=serial.log
BUPDIR=Serconlogs

if [ ! -f ${FILE} ] ; then
   echo "$0: Sorry no file ${FILE} found!"
   exit 1
fi

mkdir -p ${BUPDIR}

# -rw-r--r--  1 j65nko  j65nko  146366 Feb  3 05:03:54 2010 serial.log
#    1        2   3       4       5     6   7    8      9     10

listing=$(ls -lT ${FILE})

# echo ${listing} | awk '{ print $6, $7, $8, $9 }'
# FILEnew=$(echo ${listing} | awk '{ printf("%s_%s_%s_%s_%s" , $9,$6,$7,$8,$10) }')
# echo $FILEnew
# 2010_Feb_3_05:03:54_serial.log
# we need to align the day in a field of 2 

FILEnew=$(echo ${listing} | awk '{ printf("%s_%s_%02u_%s_%s" , $9,$6,$7,$8,$10) }')
# echo $FILEnew
# 2010_Feb_03_05:03:54_serial.log

#echo mv ${FILE} ${BUPDIR}/${FILEnew}
mv ${FILE} ${BUPDIR}/${FILEnew}

ls -l ${BUPDIR}

In the following I first create a fake new file to be archived then run the script

$ echo aap >serial.log
$ ./arch-serial.log

The OpenBSD snapshots that I download by default end up in a directory Snapshots. To archive them before fetching a new snapshot, I use this script.

#!/bin/sh
# archive OpenBSD snapshots
# use the bsd.rd date in name of backup

DIR=Snapshots
BUPDIR=Snap-archive

if [ ! -d ${DIR} ] ; then
   echo "$0: Sorry no directory ${DIR} found!"
   exit 1
fi

mkdir -p ${BUPDIR}

# ls -lT Snapshots/bsd.rd
# -rw-r--r--  1 j65nko  j65nko  2162 Jan 28 18:10:51 2010 Snapshots/bsd.rd
#    1        2   3       4      5    6   7    8      9     10
listing=$(ls -lT ${DIR}/bsd.rd)

DIRnew=$(echo ${listing} | awk '{ printf("%s_%s_%02u_%s") , $9,$6,$7,$8 }')
#echo $DIRnew
#exit


# rename $DIR 
mv ${DIR} ${DIRnew}
# move renamed directory into archive directory
mv ${DIRnew} ${BUPDIR}/${DIRnew}

ls -l ${BUPDIR} ${BUPDIR}/${DIRnew}

# -- end of file

The similarities with the script in the previous script are obvious.
The output when run with the -vx shell options:

sh -vx arch-snap                                                     
#!/bin/sh
# archive OpenBSD snapshots
# use the bsd.rd date in name of backup

DIR=Snapshots
+ DIR=Snapshots
BUPDIR=Snap-archive
+ BUPDIR=Snap-archive

if [ ! -d ${DIR} ] ; then
   echo "$0: Sorry no directory ${DIR} found!"
   exit 1
fi
+ [ ! -d Snapshots ]

mkdir -p ${BUPDIR}
+ mkdir -p Snap-archive
