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
#

NAME

       zip_source_file - create data source from a file

SYNOPSIS

       struct zip_source * zip_source_file(struct zip *archive, const char *fname); "zip_uint64_t start" "zip_int64_t len"

DESCRIPTION

       The  function zip_source_file creates a zip source from a file.	zip_source_file opens fname and reads len bytes from offset start from it.
       If len is 0 or -1, the whole file (starting from start ) is used.

       The fie is opened and read when the data from the source is used, usually by zip_close.

RETURN VALUES

       Upon successful completion, the created source is returned.  Otherwise, NULL is returned and the error code in archive is set  to  indicate
       the error.

ERRORS

       zip_source_file fails if:

	      [ZIP_ER_INVAL]
		  fname, start, or len are invalid.

	      [ZIP_ER_MEMORY]
		  Required memory could not be allocated.
