What is $echo?

[rlebron-bioinfo]

Hi,

Your Bash scripts contain $echo followed by an integer and a message. For example:

$echo 2 "check fragment length"

Since $echo is neither an environment variable nor a variable defined in the script, it returns errors. Could you explain to me what $echo is and why it is followed by an integer?

Thanks in advance.

Best regards,

It is defined in the TEMP2 file (in the root of the repository).

BINDIR=$(dirname `readlink -f $0`) && export BINDIR=${BINDIR}/bin
export echo="${BINDIR}/echo0”
