NO you can NOT pipe this as it is creating its own filesnames, one per page, based on a given 'basename'. You can NOT redirect this to a pipe. HOWEVER. If this is a script (sh, bash or zsh) you can do this.. =======8<-------- #!/bin/sh input="$1" output="$2" TMPDIR=/tmp/pdf_pages_$$ trap 'rm -rf $TMPDIR; exit 1' 1 2 3 15 trap 'rm -rf $TMPDIR; exit 0' 0 mkdir $TMPDIR pdftoppm -r 300 -f 1 -l 1 "$input" $TMPDIR/tex convert tex-000001.ppm "$output" exit 0 =======8<-------- The 'trap's in the above ensures the files are cleaned up on any exit (except a unstoppable kill or '9' signal).
