Detect ssh login from ~/.bashrc
# If you put this check inside ~/.bashrc you can detect bash session opened by ssh-logins :)

Check that all files under current dir are readable. I use it to check the decrypted-version of files ofan EncFs dir... to check that the decrypted files are all ok... if the EncFs dir is in Dropbox and the upload/sync fails, then the decrypted-version will have errors, which can be spoted with this simple script
#!/bin/bash
function shw_grey { echo -e '\033[1;30m'"$1"'\033[0m'; }
function shw_norm { echo "$1"; }
function shw_info { echo -e '\033[1;34m'"$1"'\033[0m'; }
function shw_warn { echo -e '\033[1;33m'"$1"'\033[0m'; }
function shw_err { echo -e '\033[1;31mERROR: '"$1"'\033[0m'; }
shw_info "Check starting..."
find . -type f -exec wc -l \{\} 2>&1 \; | grep error
shw_info "Check finished"
