SEARCHED=<file>
for f in $(find . -type f -name "*jar"); do echo "Searching in $f: "; jar tvf $f | grep $SEARCHED; done

Autre solution (moins bien)

#!/bin/bash

find . -type f -name "*jar" -exec sh -c '
export FILE
for FILE
do 
  jar tf $FILE | grep -H --label=$FILE $1
done' sh {} +

Useful RAID commands :

# Conf mdadm
cat /etc/mdadm.conf

# Current md stats
cat /proc/mdstat

# detail on a MD device :
mdadm --query --detail /dev/md3

# detail on partition
mdadm --examine /dev/sda3

Complete with OVH RAID help

# Copy partition table from safe disk to new disk (for GPT partition - see fdisk -l)
sgdisk -R /dev/newdisk /dev/safedisk

# afterwards, you have to randomize the GUID on the new hard disk to ensure that they are unique (from [howto forge](https://www.howtoforge.com/tutorial/linux-raid-replace-failed-harddisk/))
sgdisk -G /dev/sdb

# check partitions are copied 
sgdisk -p /dev/safedisk
sgdisk -p /dev/newdisk

# Add each partition to RAID cluster :
mdadm --manage /dev/mdX2 --add /dev/newdiskX2
mdadm --manage /dev/mdX1 --add /dev/newdiskX1

# follow reconstruction with 
mdam --detail /dev/mdX
or 
cat /proc/mdstat
#  Rebuild Status : 21% complete

Pour ajouter des fichiers git-lfs

1. Ajouter des fichiers Examples

git lfs track <mybigfile.jar>
git lfs track "**/*jar"
git lfs track "**/*jar"
git config lfs.fetchinclude "textures,images/foo*"
git config lfs.fetchexclude "media/reallybigfiles"

2. Commiter le nouveau tracking

git add --renormalize
git lfs migrate info
git lfs migrate import --include="mybigfile.jar"
git lfs migrate info

1. Lister les fichiers LFS

git lfs ls-files -a -s

Pour nettoyer entre autre les historiques des fichiers LFS :

1. download jar
2. create a clean copy the repo (git clone)
3. execute :

java -jar bfg-1.14.0.jar --delete-files database-hpa.tar.gz  hpa-portal
git reflog expire --expire=now --all && git gc --prune=now --aggressive
