bash berries is a set of tiny bash scripts that can do some work for you if you are an admin or a developer.
Not only scripts are being provided by this project, but also include files that help you to write our own bash scripts more quickly. All bash berries have been tested on the latest stable Ubuntu LTS and macOS releases. If you don't set any parameters for a script, a short help will be printed.

The bash berries in detail
bigfiles v1.1.0, Copyright 2017 Johann N. Loefflmann Determines the biggest files in a directory and it's subdirectories Usage: bigfiles [-o] [-g greater] [-n max_files] [path] Options: -o print the owners of the biggest files. -g greater a file is a big file if its file size is greater than the greater value. You may append k, M, G and T for kilo, Mega, Giga, and Tera. If greater is omitted, greater is set to 0. -n max_files specifies the maximum number of big files. If max_files is omitted or if max_files is set to 0, all files will be printed that matches -g. Parameters: path specifies the directory to be traversed. If path is omitted, this help will be printed. Examples: bigfiles -g 1M . all files greater than 1 MB in the current working directory and below. bigfiles -o -n 25 -g 1G / 25 biggest files > 1 GB in the root directory and below including a summary of the owners of those files.
latlng v1.0.0, Copyright 2017 Johann N. Loefflmann Determines both latitude and longitude of a location. The script uses the Google Maps web service. Usage: latlng [-c][-i] [location] Options: -c output as one line separated by a comma -i input in interactive mode Parameters: location the location as a string Examples: latlng "Statue of Liberty" determines lat and lng of the Statue of Liberty latlng -ic reads input from the user in order to determine lat and lng
lines v1.0.0, Copyright 2017 Johann N. Loefflmann Extracts a block of lines from a textfile Usage: lines [-i] [-b number] [-e number] [-H number] [-T number] [file [begin [end]]] Options: -b number If begin is a string and if it matches more than one line, you can specify a particular match number. -e number If end is a string and if it matches more than one line, you can specify a particular match number. -i Ignore case. Perform case insensitie matching. By default, the search algorithm is case sensitive. -H number A positive number cuts the head of the output. A negative number extends the head of the output. -T number A postivie number extends the tail of the output. A negative number cuts the tail of the output. Parameters: file Specifies the textfile that needs to be processed. If file is omitted, this usage will be printed. begin Specifies the search string in order to find the "begin". If begin is a string, it searches for the first occurence in the file. If begin is an integer, it specifies a line number (starting with 1). end Specifies the search string in order to find the "end". If end is a string, it searches for the first occurence starting with the line that is specified by "begin". If end is an integer, it specifies a line number (starting with 1). Examples: lines log.txt 20 40 Prints line number 20 to line number 40 from the file called log.txt lines -T -1 verylong.log "^2017-08-06" "^2017-08-07" Prints lines from the log file called verylong.log, starting with the line that starts with "2017-08-06" and ending with the line that starts with "2017-08-07", but not printing out that last ending line
update_jdk v1.12.0, Copyright 2018 Johann N. Loefflmann Downloads the latest x64 JRE/JDK tarball resp. the latest tzupdater zip from the web, extracts it and creates/updates a symlink called <type>_latest resp. tzupdater.jar. Supports multiple sources, such as oracle.com, java.com, jdk.java.net, adoptopenjdk.net, and zulu.org. The latest timezone database can be applied to the requested JRE/JDK as well so that you have the most possible up to date JRE/JDK within a Java family from your preferred source. And since the symlink always points to the latest JRE/JDK you can update the JRE/JDK both fast and comfortable. The OS flavor of the JRE/JDK is determined by the OS that you are running. Both GNU/Linux and macOS are supported. Usage: update_jdk [ [-h] | [-a] [-d] [-f] [-k] [-s source] [-t type] [path] ] Options: -a accept license. That is a required option if you want to download the JRE, JDK or tzupdater from the Oracle site (-t oracle.com). Please read the license at www.oracle.com/technetwork/java/javase/terms/license/index.html resp. at http://www.oracle.com/technetwork/java/javasebusiness/downloads/ L-> tzupdater-lic-354297.txt and allow the script to download the package by specifying this option. -d dry run. Don't download the JRE, JDK or tzupdater, just inform the user. -f force. Even if we have the JRE, JDK or tzupdater already, update it again. -h prints this help. -k keep the downloaded .tar.gz resp. .zip, don't remove it at the end. -s source. Supported values are oc or oracle.com (Oracle binaries, default) jc or java.com (Oracle binaries) jn or jdk.java.net (OpenJDK binaries) an or adoptopenjdk.net (OpenJDK binaries) zo or zulu.org (OpenJDK binaries) -t type. Valid value depends on the source. For -s oracle.com it can be jdk (latest JDK) jre (latest JRE) sjre (latest Server JRE) tzupdater (latest tzupdater) For -s java.com it can be jre (latest JRE) For -s jdk.java.net this can be openjdk12 (OpenJDK 12) openjdk11 (OpenJDK 11) openjdk10 (OpenJDK 10) For -s adoptopenjdk.net it can be openjdk10 (OpenJDK 10 with Hotspot) openjdk10-openj9 (OpenJDK 10 with OpenJ9) openjdk9 (OpenJDK 8 with Hotspot) openjdk9-openj9 (OpenJDK 8 with OpenJ9) openjdk8 (OpenJDK 8 with Hotspot) openjdk8-openj9 (OpenJDK 8 with OpenJ9) For -s zulu.org it can be jdk10 jdk9 jdk8 -v version. Prints out the version of this script. -z after the JRE or JDK has been downloaded and extracted, the latest tzupdater will be downloaded and applied to the JRE or JDK. Requires -a to work. Parameters: path specifies the path where the JRE, JDK or tzupdater should be stored. It will be created if it doesn't exist. If omitted, .<type>/ will be used. Examples: ./update_jdk -a updates the JRE in ./jre/ and it creates a symlink called jre_latest there. ./update_jdk -az myjres updates the JRE in myjres and it updates the symlink called jre_latest there. Additionally the latest timezone updater is being downloaded and called so that the JRE's timezone database also gets updated. ./update_jdk -a -t jdk /opt/java/ updates the JDK in /opt/java/ and it updates a symlink called jdk_latest there. ./update_jdk -a -t tzupdater /opt/java/ updates the tzupdater in /opt/java/ and it updates a symlink called tzupdater.jar there. ./update_jdk -az -s an -t openjdk10 downloads both the latest tzupdater from oracle.com and the latest OpenJDK10 build from adoptopenjdk.net, applies the latest timezone database from IANA to the OpenJDK by calling the tzupdater tool. Symlink called .openjdk10/openjdk10_latest will point to the latest and updated OpenJDK10 build.
update_property v1.2.0, Copyright 2017,2018 Johann N. Loefflmann Updates the value of a key/value pair in a property file. The script saves existing comments and also the order of the properties. Usage: update_property [-d <delimiter>] [-e] [-f] [-q] [file key value] Options: -a keeps the existing value and appends the new value. -d delimiter, delimits the key and the value. If omitted the equal sign is assumed. -e echo the updated line of the file. -f force to append the key/value pair to the file even if the key is not in the property file yet. -p keeps the existing value and prepends the new value. -q set quotes around the value when writing the value. Parameters: file specifies the file that needs to be updated. key specifies the key in the property file. value specifies the value for the key. Examples: update_property -f -q app.conf mykey "new value" updates the key called "mykey" with the value called "new value" with quotes around the value in the app.conf property file, and creates the key/value pair if the key does not exist. update_property -d ' ' -e /etc/openvpn/vpn.conf remote "my-server-1 1194" updates the key called "remote" in the property file that has a blank as the delimiter, it also echoes the modified line.
update_bashberries v1.2.0, Copyright 2017-2018 Johann N. Loefflmann Downloads the latest bash scripts from the bashberries project on github and updates any existing scripts in the directory that has been specified. Usage: update_bashberries [-n] <directory> Options: -n don't check for a new update_bashberries script Parameter: directory the directory where the scripts should be stored Examples: ./update_bashberries . updates the bashberries in the current working directory bash <(curl -Ls http://bit.ly/update-bashberries) ~/bin updates the bashberries in ~/bin with just this line
update_tzdatabase v1.0.2, Copyright 2017-2018 Johann N. Loefflmann Downloads the latest timezone data from iana.org, calculates the necessary sha256 digest by calling jacksum, and updates the timezone database of your Java Runtime Environment by calling tzupdater.jar Usage: update_tzdatabase [ [-h] | [-j java-binary] [-s jacksum.jar] [-t tzupdater.jar] ] Options: -h prints this help. -j java location of the java binary. If omitted, default java is used. -s jacksum.jar location of the jacksum.jar file. If omitted, jacksum.jar is expected in the script dir. -t tzupdater.jar location of the tzupdater.jar file. If omitted, tzupdater.jar is expected in the script dir. Examples: update_tzdatabase updates the tzdatabase of the default JRE. sudo ./update_tzdatabase -j \$(type -P java) updates the tzdatabase of the default JRE using root permissions.
