BASH

Git - Mass Updater

BASH, Script, Git

Intro

Let’s assume you have a bunch of GIT Repos in a Folder like this:

/project1/
    /repo1/
    /repo2/
    /repoN/

and you would like to update all of them ? here a little helper.

  • Loop over all Folders
  • check if ‘.git’ exists
  • if so, do a git pull –all

Script

Copy/Paste it to your Terminal and you get a executable Script called ‘git_update_all.sh’.

cat << 'EOF' > git_update_all.sh
#!/usr/bin/env bash

# Get the current script directory
script_dir=$(dirname "$(readlink -f "$0")")

# Change into each directory in the script folder
for dir in "$script_dir"/*; do

    if [ -d "$dir" ]; then

        cd "$dir" || exit 1

        if [ -d ".git" ]; then

            echo "Updating Git repository in $dir"
            git pull --all

        else

            echo "Skipping $dir - not a Git repository"

        fi

        cd "$script_dir" || exit 1

    fi

done

echo "Git update for all repositories completed."
EOF

# make it executable
chmod u+x git_update_all.sh

Usage

and then run it, like it, use it :)

SOA Checker

BASH, DNS, SOA

Intro

this is a little script which reads the Name Servers for a given Domain, and then asks the NameServer for the SOA of this Domain.

Script

cat << 'EOF' > soachecker.sh
#!/usr/bin/env bash

# Little SOA & Serial Checker, v0.1, @stoege

tmpfile=$(mktemp)

# Check Args
echo
if [ $# -eq 0 ]; then
  d="stoege.net"
  echo -e "No argument provided. use \033[1m'${d}'\033[0m"
elif [ $# -eq 1 ]; then
  d="$1"
  echo -e "Domain \033[1m'${d}'\033[0m provided"
else
  echo -e "\033[1mmore than one arguments provided. Exit 1.\033[0m"
  exit 1
fi

# Build File
for i in $(dig +short NS ${d} |tr '\n' ' '); do
  echo -e "\ndig +short SOA \033[1m@${i}\033[0m ${d}"
  dig +short SOA @${i} ${d} |tee -a ${tmpfile}
done

# uniq & count
echo
cat ${tmpfile} |sort |uniq -c |awk '{ printf "%d x Serial: %s\n", $1,$4 }'

# cleanup
rm ${tmpfile}

echo
exit 0
EOF
chmod u+x soachecker.sh

Run it

$ ./soachecker.sh stoege.net

Domain 'stoege.net' provided

echo dig +short SOA @ns3.noflow.ch. stoege.net
ns1.noflow.ch. hostmaster.noflow.ch. 2023050124 3600 900 1209600 1800

echo dig +short SOA @ns1.noflow.ch. stoege.net
ns1.noflow.ch. hostmaster.noflow.ch. 2023050124 3600 900 1209600 1800

echo dig +short SOA @ns2.nolink.ch. stoege.net
ns1.noflow.ch. hostmaster.noflow.ch. 2023050124 3600 900 1209600 1800

3 x Serial: 2023050124
