do mvn clean in subdirs to free disk space

find -name pom.xml | while read f; do cd $(dirname "$f"); mvn clean; cd -; done;
this command is used to locate all pom.xml files, access the dir and do a mvn clean, but I do recommend you to disable network interfaces to not download dependencies packages to be faster.

  • For disk space constraint testing. Leaves a little space available for creating temp files, etc. Easily free up the used disk space again by deleting the dummy00 file. Can tailor the testing by building smaller 'blocks' to suit the needs of the testing. WARNING: do not do this to the '/' (root) filesystem unless you know what you are doing... on some systems it could crash the OS.

  • Often you need to find the files that are taking up the most disk space in order to free up space asap. This script can be run on the enitre filesystem as root or on a home directory to find the largest files. Show Sample Output

  • Instead, install apt-get install secure-delete and you can use: -- srm to delete file and directory on hard disk -- smem to delete file in RAM -- sfill to delete "free space" on hard disk -- sswap to delete all data from swap

What Others Think

A few things spring to mind: . First, I'd prevent any accidents, by checking that cd succeeds before running mvn clean. cd $(dirname "$f") && mvn clean . I might also put the cd in a subshell to avoid any side-effects ... do (cd $(dirname "$f") && mvn clean); done . Finally, I'd drop dirname and let bash variable substitution do the work: cd "${f%/*}" . The final command is: find -name pom.xml | while read f; do (cd "${f%/*}" && mvn clean); done; . Or... ;-) find -name pom.xml -printf '(cd "%h" && mvc clean)\n' | sh
