# Rsyncr (Rsync Retry) 2016 David Mcanulty
# Runs rsync, retrying on errors up to a maximum number of tries with incremental backoff (delay)
# Based on idea from https://gist.github.com/iangreenleaf/279849 by iangreenleaf 2011
# Set your max rsync retries here
max_retries=50
# Trap interrupts (ctrl-c) and exit instead of continuing the loop

Created January 2, 2014 23:05
Puppet parser/lint git pre-commit hook script. Improves on versions I've seen around the net
#!/bin/bash

else
echo -e "Error, missing required item(s) from path.\n Requires: git puppet-lint\n\nFound:\n${requires}"

tsaavik / kill-ipc.sh
Last active October 12, 2021 21:54
Kill all IPC semaphores. Useful when someone forgets to properly clean up. Borrowed and enhanced from a stackoverflow question.
#!/bin/bash
PATH="/bin:/usr/bin"
ipcs
read -p "press enter to kill all the ipc process owned by ${USER}"
IPCS_S=$(ipcs -s | egrep "0x[0-9a-f]+ [0-9]+" | grep ${USER} | cut -f2 -d" ")
IPCS_M=$(ipcs -m | egrep "0x[0-9a-f]+ [0-9]+" | grep ${USER} | cut -f2 -d" ")
IPCS_Q=$(ipcs -q | egrep "0x[0-9a-f]+ [0-9]+" | grep ${USER} | cut -f2 -d" ")

tsaavik / mp3-tuner.sh
Last active October 12, 2021 21:56
Inspired by the tuner scripts we used at mp3.com, this sets some performance options for hard disks, and has some specific optimizations for SSD/NVMEs
#!/bin/bash
# Tweak hard drive performance stuff
for drive in sda sdb sdc sdd; do
if [[ -e /dev/${drive} ]] ;then
#increase readahead buffer on sata devices
/sbin/blockdev --setra 2048 /dev/${drive}
echo 1024 > /sys/block/${drive}/queue/read_ahead_kb
if smartctl -a /dev/${drive} |grep SSD;then
#SSDs do not have latency issues like traditional hdd so we tweak
echo "/dev/${drive} is a SSD, tweaking proc entries"
