appendFileTar(){
# Desc: Processes first file and then appends to tar
# Usage: appendFileTar [file path] [name of file to be inserted] [tar path] [temp dir] ([cmd1] [cmd2] [cmd3] [cmd4]...)
- # Version: 1.0.0
+ # Version: 1.0.2
# Input: arg1: path of file to be (processed and) written
# arg2: name to use for file inserted into tar
# arg3: tar archive path (must exist first)
# arg5+: command strings (ex: "gpsbabel -i nmea -f - -o kml -F - ")
# Output: file written to disk
# Example: decrypt multiple large files in parallel
- # appendArgTar /tmp/largefile1.gpg "largefile1" $HOME/archive.tar /tmp "gpg --decrypt" &
- # appendArgTar /tmp/largefile2.gpg "largefile2" $HOME/archive.tar /tmp "gpg --decrypt" &
