I know this is 4 years late but for anybody else that might run across this question you can exclude from Dir the same way you would exclude from Bash wildcards: Dir[“lib/{[!errors/]**/*,*}.rb”] Which will exclude any folder that starts with “errors” you could even omit the / and turn it into a wildcard of sorts … Read more
Docker doesn’t expand ARG values in the RUN command. Instead, it injects the ARG as an environment variable. The shell itself expands the variable, and all of the Linux shells I’ve used behave differently based on the type of quote. The single quotes direct the shell not to expand anything, and you only need to … Read more
Thanks to all of you for spending your valuable time in finding answer to my question here. However I am now answering my own question since I’ve found a hack way to get this pid on bash ver < 4 (will work on all the versions though). Here is the command: echo $$; ( F=’/tmp/myps’; … Read more

Create a bash script called client.sh: #!/bin/bash cat someFile while read FOO; do echo $FOO >&3 if [[ $FOO =~ `printf “.*\x00\x1c.*”` ]]; then break fi done Then invoke netcat from your main script like so: 3>&1 nc -c ./client.sh somehost 1234 (You’ll need bash version 3 for the regexp matching). This assumes that the … Read more
Change file2.sh to: #!/bin/bash echo “from file2: ${BASH_SOURCE[0]}” Note that BASH_SOURCE is an array variable. See the Bash man pages for more information.
Pipe it to less -F aka –quit-if-one-screen: Causes less to automatically exit if the entire file can be dis- played on the first screen.
Typically error and output files are given as pbs directives in the qsub script or as command line options to the qsub script like so: #! /bin/bash #PBS -q queue_name #PBS -A account_name #PBS -l nodes=12:ppn=12 #PBS -l walltime=18:00:00 #PBS -e /mypath/error.txt #PBS -o /mypath/output.txt or as a command line option to qsub like so: … Read more
