Filesystem integrity checker-script: check-file-by-name.sh

[lab-at-nohl]

If you ever have the need for checking a Tine filesystem, the following script compare the SHA1-filename against its checksum (my case was a big copy action to an encrypted remote filesystem). It takes one parameter, the directory where Tine stores its files.

See check-file-by-name.sh <TINE-FILESDIR>:

#!/bin/bash

TWIDTH=$(tput cols)
TOTAL=$(find $1 -type f | wc -l)

function check_file() {
  FNAME=$(basename $(dirname $1))$(basename $1)
  FSUM=$(sha1sum $1 | awk '{print $1}')
  [[ "$FNAME" == "$FSUM" ]] && return 0
  return 1
}

STEP=$((TOTAL / TWIDTH))
C=0
for F in $1/**/*; do
 C=$((C + 1))
 STEP=$((STEP - 1))
 if [ $STEP -lt 1 ]; then
  STEP=$((TOTAL / TWIDTH))
  echo -n '#'
 fi

 check_file $F
 if [ $? -eq 1 ]; then
   echo # new line because gauge
   echo "PROBLEM: $F"
   for i in $(seq 0 $((C / STEP))); do
    echo -n "#"
   done
 fi

done

echo
echo "Files scanned $C - found $TOTAL"

As far as I know, file metadata like access/modification date does not matter for Tine.

hi,

thanks for the script - you might even add this to https://github.com/tine-groupware/tine/tree/main/scripts if you like ...

that's right.
