I have the following array inside a program:  ... #code  $packages = [     'git',        # version control     ...    'iftop',      # monitor network usage by ip    'iotop',      # monitor io usage  ]  ... #more codeI want to use awk to print lines from the first occurrence of $packages to the first ending ], after the occurrence of $packages.How can I do this?
Print from first instance text A to first instance of text B
awk
Iterate over the records, keep an identifier for $packages, print lines when the identifier is set, and exit after printing when you find next ]:awk '/\$packages/ {c=1; print; next} /\]/ {print; exit}; c{print}'Example:% cat file.txt   ... #code  $packages = [     'git',        # version control     ...    'iftop',      # monitor network usage by ip    'iotop',      # monitor io usage  ]  ... #more code  ... #code  $packages = [     'git',        # version control     ...    'iftop',      # monitor network usage by ip    'iotop',      # monitor io usage  ]  ... #more code% awk '/\$packages/ {c=1; print; next} /\]/ {print; exit}; c{print}' file.txt     $packages = [     'git',        # version control     ...    'iftop',      # monitor network usage by ip    'iotop',      # monitor io usage  ]
