Tar usage / Tar Cheat Sheet

Tar Usage / Cheat Sheet

Compress a file or directory

e.g: tar -czvf name-of-archive.tar.gz /path/to/directory-or-file

  • -c: Create an archive.
  • -z: Compress the archive with gzip.
  • -v: makes tar talk a lot. Verbose output shows you all the files being archived and much.
  • -f: Allows you to specify the filename of the archive.

Jenkinsfile idiosynchrasies with escaping and quotes
node {
echo 'Results included as an inline comment exactly how they are returned as of Jenkins 2.121, with $BUILD_NUMBER = 1'
echo 'No quotes, pipeline command in single quotes'
sh 'echo $BUILD_NUMBER' // 1
echo 'Double quotes are silently dropped'
sh 'echo "$BUILD_NUMBER"' // 1
echo 'Even escaped with a single backslash they are dropped'
sh 'echo \"$BUILD_NUMBER\"' // 1
echo 'Using two backslashes, the quotes are preserved'
sh 'echo \\"$BUILD_NUMBER\\"' // "1"

Persistent pipes/circular buffers for Linux

📂 Persistent "pipes" in Linux

In a project I'm working on I ran into the requirement of having some sort of persistent FIFO buffer or pipe in Linux, i.e. something file-like that could accept writes from a process and persist it to disk until a second process reads (and acknowledges) it. The persistence should be both across process restarts as well as OS restarts.

AFAICT unfortunately in the Linux world such a primitive does not exist (named pipes/FIFOs do not persist
