Top Forums Shell Programming and Scripting Remove files having 0 byte or only header Post 302993940 by jim mcnamara on Thursday 16th of March 2017 01:00:58 PM

Okay. You need to describe how to tell a header-only file from a file you want to keep.
If is simply size. Pretend example -

You want to delete 36 byte files and smaller, this finds files smaller than 37 and created in the last 24 hours:

Code:
find /path/to/files -type f -size -37c -ctime -1 -exec rm {} \;

One line files work this way:
Code:
find /path/to/files -type f  -ctime -1 |
while read fname 
do  
       sz=`cat $fname | wc -l`   # Not a UUOC done to get just a line count
       [ $sz -lt 2 ] && rm $fname
done

clm residue(1)							  USER COMMANDS 						    clm residue(1)

  NAME
      clm residue - extend clustering of subgraph to clustering of graph.

      clmresidue  is  not  in  actual fact a program. This manual page documents the behaviour and options of the clm program when invoked in mode
      residue. The options -h, --apropos, --version, -set, --nop are accessible in all clm modes. They are described in the clm manual page.

  SYNOPSIS
      clm residue -icl fname (input clustering) -imx fname (input graph) [-rpm fname (residue projection matrix)]  [-o	fname  (output	clustering
      file)]

  DESCRIPTION
      The cluster file presumably contains a clustering of a subgraph of the graph G contained by the matrix file, implying that the row domain of
      that clustering is a subset of the node domain of the graph. clm residue will compute  a	simple	upwards  projection  of  that  clustering,
      resulting in a clustering of G.

  OPTIONS
      -imx fname (input graph)

      -icl fname (input clustering)

      -rpm fname (residue projection matrix)
	The name for the file in which the residue projection matrix is stored.  It contains for each node and for each cluster in the input clus-
	tering the combined weight of the (edges to the) neighbours of that node in that cluster.  The default output file name is out.rpm.

      -o fname (output clustering file)
	The name for the file in which the majority vote projection clustering is stored. Aka the majority vote projection clustering storage file
	name.

	This  embodies	a very crude approach to distributing the missing nodes in the input clustering onto that same cluster. For each node, the
	cluster is taken for which the residue projection is the largest (see above). The residue (i.e. the set of  missing  nodes)  is  initially
	viewed	as  a  cluster;  the set of nodes for which the projection is largest for the residue itself will form a new cluster, if it is not
	empty.

	By default output is sent to STDOUT.
