Full Discussion: Extract date from filename and create a new file
Top Forums Shell Programming and Scripting Extract date from filename and create a new file Post 302501503 by Chubler_XL on Thursday 3rd of March 2011 06:31:13 PM
Old 03-03-2011
Code:
FILENAME="/dprod/informatica/Fuentes/CRED20102009.csv"
DIRNAME=$(dirname $FILENAME)
echo $FILENAME | sed 's/^.*\(..\)\(..\)\(....\)\....$/[Comercial.AACPWM001]\n$$Date = \3\2\1 aaammdd format/' > $DIR/Parameters.txt

The string in your parameters.txt file is just about long enough to fetch the date into another shell var and then cat it out (this also makes it easier to update the parameters format at a later date):

Code:
FILENAME="/dprod/informatica/Fuentes/CRED20102009.csv"
DIRNAME=$(dirname $FILENAME)
DATESTR=$(echo $FILENAME | sed 's/^.*\(..\)\(..\)\(....\)\....$/\3\2\1/')
 
cat <<EOF > $DIR/Parameters.txt
[Comercial.AACPWM001]
\$\$Date = $DATESTR aaammdd format
EOF

LEARN ABOUT OSX

info

INFO(1) 							   User Commands							   INFO(1)

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
