Top Forums UNIX for Dummies Questions & Answers Deletes those files in a directory ? Post 302402873 by jim mcnamara on Wednesday 10th of March 2010 10:19:41 PM

Code:
#!/bin/ksh
ls $1 > one
ls $2 > two
awk 'FILENAME=="one" {arr1[$0]++}
       FILENAME=="two" && $0 in arr1 {print $0} ' one two > dupfiles
# this PART IS DANGEROUS
while read fname
do
   rm $2/$fname
done < dupfiles

This creates a file that has the names of the duplicates found in dir==$2 then deletes them from directory $2. Be careful this script could clobber something you really need. It also DOES NOT consider links, which could be important. All in all this script is not a great idea - but I think it does what you specifed

MAKE-like build that deletes orphans?

I have a complex multi-stage (media conversion and formatting) build process that leaves orphan target files needing deleting automatically (i.e. by reference only to the build rules themselves, not any parallel config) upon each regular build. Since MAKE cannot do this, what can? Thanks. (4 Replies)

NAME
info - read Info documents SYNOPSIS
info [OPTION]... [MENU-ITEM...] DESCRIPTION
Read documentation in Info format. OPTIONS
--apropos=STRING look up STRING in all indices of all manuals. -d, --directory=DIR add DIR to INFOPATH. --dribble=FILENAME remember user keystrokes in FILENAME. -f, --file=FILENAME specify Info file to visit. -h, --help display this help and exit. --index-search=STRING go to node pointed by index entry STRING. -n, --node=NODENAME specify nodes in first visited Info file. -o, --output=FILENAME output selected nodes to FILENAME. -R, --raw-escapes output "raw" ANSI escapes (default). --no-raw-escapes output escapes as literal text. --restore=FILENAME read initial keystrokes from FILENAME. -O, --show-options, --usage go to command-line options node. --subnodes recursively output menu items. -w, --where, --location print physical location of Info file. --vi-keys use vi-like and less-like key bindings. --version display version information and exit. The first non-option argument, if present, is the menu entry to start from; it is searched for in all `dir' files along INFOPATH. If it is not present, info merges all `dir' files and shows the result. Any remaining arguments are treated as the names of menu items relative to the initial node visited. EXAMPLES
info show top-level dir menu info emacs start at emacs node from top-level dir info emacs buffers start at buffers node within emacs manual info --show-options emacs start at node with emacs' command line options info -f ./foo.info show file ./foo.info, not searching dir REPORTING BUGS
