samos123 / backup_corrupted_gzip_files
Created March 1, 2014 03:32
Had some problem with cado-nfs which had a bunch of gzipped files which were corruped so tried to decompress them, if the decompression failed it will automatically move the file to upper directory.
ls *.gz -1 | xargs -I {} sh -c "gzip -d {} || true" 2>&1 | awk '{ print $2}' | sed 's/:$//' | xargs -t -I {} mv {} ../{}_bcorrupted

Created April 3, 2014 02:07
Playing around with bash, at the university I have to manually set my internet configuration on a specific network. Thought let's automate it
#!/bin/bash
set -xi
sudo ip addr add 172.16.4.99/22 dev eth0
GATEWAY=$(ip route show | grep default | awk '{ print $3}')
echo "Current default gateway: $GATEWAY"
if [ -z $GATEWAY ]
then
sudo ip route del default $GATEWAY
