process substitution

syntax error near unexpected token `('

I got the error message when I used command like:

program <(zcat myfile1.gz)<(zcat myfile2.gz)

in a bash script. It works well in my terminal, but when I submit the script to cluster and it always return the error message.

Finally I got the key from Mitch's blog:

It's called process substitution for piping the stdout of multiple commands. Process substitution is not a POSIX compliant feature and so it may have to be enabled via:

set +o posix

After I set the POSIX, it works well! It seems that POSIX is not enabled on the node where the job was submitted.

Super duper command: find

• Find files with filename containing WORD
  find -type f -name \*WORDS\*  
• Find files by name in case-sensitive way, e.g. containing word or Word...
  find -type f -iname \*word\*
• Find files with name containing "word", "Word" etc., but not "WORD"
  find -type f -iname \*word\* -not -name \*WORD\*
• Unzip all *.tar.gz files
  find -type f -name \*.gz -exec tar -zxvf {} \;
• Use pipe in find command
  find ~/scratch/RNAseq/ -type f -name clean.fa -printf "a=\`echo %p | cut -f6- -d'/' | sed 's/\//./g'\`; cp %p \$a \n" | sh
  # copy /home/dongx/scratch/RNAseq/****/xxxx/clean.fa to ****.xxxx.clean.fa
