Created May 16, 2017 23:01

inotifywait to exec specified command on each file change -> e.g. run "make", "pdflatex", or any other compile/upload or other command of choice! (Thanks https://superuser.com/a/181543/81861 ! )

gwpl / gen_basic_files_metadata.csv.sh

Last active May 25, 2017 14:12

Generate .csv formatted basic metadata, fast to obtain, but allowing heuristics for syncing files or initial eastimation of backup/sync coverage. ( And yes, I know that this find command will not properly encode filenames containing quotes according to csv standard )

	#!/bin/bash
	# Generate .csv formatted basic metadata, fast to obtain, but allowing heuristics for syncing files or initial eastimation of backup/sync coverage.

	fullpath="${1:-$PWD}"
	dest="${2:-"$fullpath"/basic_files_metadata.csv.gz}"
	hostname="${3:-"$(hostname)"}"
	echo "find \"${fullpath}\" -type f -exec stat --format=\"%i,%Y,%s,%m,%n\" \"{}\" \\; > \"${dest}\""
	echo "Progress in lines generated:"
	(echo "inode,modification_ts,size,hostname,mount,path";
	find "${fullpath}" -type f -exec stat --format="%i,%Y,%s,${hostname},%m,%n" "{}" \;
