Top Forums Shell Programming and Scripting Awk command to split file name Post 302468423 by ctsgnb on Tuesday 2nd of November 2010 05:04:10 PM

Code:
find ./ -name "access.*" -mtime +10 -exec gzip {} \;

or
Code:
ls -t access.* | tail +11 | xargs gzip

You should find the script that generate those files instead of try to parse them : $(date '+%Y%m%d') would be a better date format choice for naming such daily files


Code:
# fname=access.2Nov-12:15AM
# for i in $(echo "$fname" | sed 's/\(access\).\([0-9][0-9]*\)\([JFMASOND][a-z][a-z]\)-\([0-9][0-9]*\):\([0-9][0-9]*\)\([AP]M\)$/\1 \2 \3 \4 \5 \6/')
> do
> let j++
> fname[$j]=$i
> done
# echo ${fname[1]}
access
# echo ${fname[2]}
2
# echo ${fname[3]}
Nov
# echo ${fname[4]}
12
# echo ${fname[5]}
15
# echo ${fname[6]}
AM
#

in ksh :
Code:
# fname="access.2Nov-12:15AM"
# echo "$fname" | sed 's/\(access\).\([0-9][0-9]*\)\([JFMASOND][a-z][a-z]\)-\([0-9][0-9]*\):\([0-9][0-9]*\)\([AP]M\)$/\1 \2 \3 \4 \5 \6/' | read a b c d e f
# echo "nam=$a day=$b mon=$c hr=$d min=$e last=$f"
nam=access day=2 mon=Nov hr=12 min=15 last=AM
#

mcxalter(1)							  USER COMMANDS 						       mcxalter(1)

  NAME
      mcxalter - various network transformations

  SYNOPSIS
      mcxalter [-imx <fname> (specify matrix input)] [-abc <fname> (specify label input)] [-tab <fname> (use tab file)] [-o <fname> (output)] [-tf
      spec (apply tf-spec to input matrix)]

  DESCRIPTION
      This utility supplies various transformations of networks.

  OPTIONS
      -abc <fname> (label input)
	The file name for input that is in label format.

      -imx <fname> (input matrix)
	The file name for input that is in mcl native matrix format.

      -tab <fname> (use tab file)
	This option causes the output to be printed with the labels found in the tab file.  With -abc this option will, additionally, construct  a
	graph  only on the labels found in the tab file.  If this option is used in conjunction with -imx the tab domain and the matrix domain are
	required to be identical.

      -tf <tf-spec> (transform input matrix values)
	Transform the input matrix values according to the syntax described in mcxio(5).

      -o fname (output file)
