I'm writing a bash script, and I was wondering what proper programming etiquette was for piping. How many pipes is too many pipes?
My next step would be to tar those directories, then move them. I'm not asking if it's a matter of CAN I pipe it all, but SHOULD I pipe it all. As its proper to indent while in a loop, is there a unanimous rule for amount of pipes?

However, there is one thing that does bother me here. (I dont mean to start a flame war, or any problems at all, just expressing some... (8 Replies)

pfsinmulti
pfsinmulti(1) General Commands Manual pfsinmulti(1)NAME
pfsinmulti - read several streams of frames and write pfs streams to named pipes
SYNOPSIS
pfsinmulti pfsinmulti <file> [--frames f:s:t] [--skip-frames] [<file>...] -- command @1 @2 [@3 ...]
DESCRIPTION
Use this command to read several animation sequences and write them to pfsstreams. This command is useful with those pfs programs, which
take several pfs streams as arguments. For example, the following command can be used to combine two animations so that there are stitched
together:
pfsinmulti anim_a-%04d.hdr anim_b-%04d.hdr -- pfscat @1 @2
arguments @1 and @2 are replaced with named pipes for anim_a-%04d.hdr and anim_b-%04d.hdr frames respectively. command argument is obliga-
tory and it must be preceded with '--'. There should be as many @1, @2, .., @n arguments as there are animation sequences given as input.
Arguments --frames, --skip-frames and other options are handled the same way as in pfsin program. Also pfsinmulti recognizes the same file
formats as pfsin.
Technically, pfsinmulti creates a named pipe for each pfsstream, replaces @n arguments with the names of those pipes and deletes the pipes
when command finishes.
EXAMPLES
pfsinmulti image1.hdr image2.hdr -- cat @1 @2 | pfsview
Does the same as 'pfsv image1.hdr image2.hdr' but in much more sophisticated way.
SEE ALSO pfsin(1)BUGS
This command currently does not handle multiple frames given with a %d pattern in case of LDR formats: JPEG, PNG, PNM.
