comment BASH: Fifo troubles - seems selective about input
In the writer part you are using FD 4 so you are doing: done 4>"$fifoIn" Should be done 4<"$fifoIn" Also fifoIn=$(mkfifo /path/to/fifo). You need to make sure fifo exists. Then.. use while IFS= read -r line; do printf '%s\n' "$line"; done ... As Anthony suggested, use set -xv just under the shebang so you get more debugging info

@StéphaneChazelas You've a point there. I should have used -- to indicate end of options. Well the .doc suggests a file. That check is not necessarily either.

That's not what OP asked either. What it does is just copy source file to dest file. There is a shorter step though. cp /path/to/dir/{file.doc,file_copy.doc} Again, the OP wan'ts to use the positional parameter $1

comment shell scripting remote commands through ssh
@RatDon as a quick workaround you can e.g use: ctrl+z which will send a SIGTSTP to the process. Here after you can enter bg and there you go!

comment Service start fails after Capistrano2 deploy task
Please quote every expansion e.g "$PIDFILE". Don't use CAPITAL letters for normal variable names. Also use $(...) command substitution instead. Put set -x just beneath your #!/bin/sh and see if the var "$PIDFILE" is set.
