Extract

Extracts strings from each line within an ASCII file.

Argument	Description
Key	-extract
1	sourcefile
2	-string: search for a string -pos: select a position -split: split a string
3	either string or position as a number
4	-endstring, –endlen or -array
5	either a string or the word blank or a position as an integer, depending on the previous argument. With -split a comma-separated list of indices is required indicating which items should be saved.
6	targetfile

Example 1: extracts a string from each line within d:\temp\abc.txt which follows directly after "val=" and ends at the next blank.

SydroCmd -extract d:\temp\abc.txt -string val= -endstring blank d:\temp\extract.txt

Example 2: extracts a string from each line within d:\temp\abc.txt starting from position 15 with a length of 25 characters.

SydroCmd -extract d:\temp\abc.txt -pos 15 -endlen 25 d:\temp\extract.txt

Download

Downloads a file with a valid URL to the local machine.

Argument	Description
Key	-download or -downloadwget (the latter causes wget to be used for downloading)
1	URL (possibly with placeholders like {0})
2	Arguments separated by a comma filling the placeholders in the URL
3	targetfile

Example: Downloads a file from the NOAA data archive. Variables are the year, month, day.

SydroCmd -download http://nomads.ncdc.noaa.gov/modeldata/cfsv2_forecast_mm_9mon/{0}/{0}{1}/{0}{1}{2}/{0}{1}{2}00/flxf.01.{0}{1}{2}00.{3}{4}.avrg.grib.grb2  2016,12,02,2016,12 D:\temp\tmp.grb2

Replace

Replaces all strings with a new string within a file. Is able to handle current date information.

Argument	Description
Key	-replace
1	sourcefile
2	search string or DATE
3	replace string or a date in the format yyyyMMddHHmm or Now
4	targetfile (if not given, then sourcefile will be overwritten)

Date replacement

If the search string is the keyword DATE, dynamic date replacement takes place:

• The replace string must then be a date in the format yyyyMMddHHmm or Now.
• In the sourcefile, the placeholder to be replaced must be given as follows: {DATE|ValidFormatstring|ValidNumber,DateInterval}, where
  • ValidFormatstring: a date format string consisting of e.g. yyyy, MM, dd, HH, mm (see here for more options)
  • ValidNumber: 0, +2, -5 or any other integer (adds/subtracts the number of years, months, days, hours, minutes as given with the number)
  • DateIntervall= y, M, d, h, m (is used to add the ValidNumber to the date)

Example: {DATE|dd|+1,d} with a replace date of 30/12/2017 results in 31 (given date + 1 day, expressed as date (dd)).

Examples

Example 1: simple replacement of "hello" with "goodbye". The sourcefile will be overwritten.

SydroCmd –replace d:\temp\abc.txt hello goodbye

Example 2: with date information

In this example the first argument is the keyword DATE indicating that date information is used. If this string is found it will be replaced by the date given in the next argument (here 5/12/2016 00:00). In the file abc.txt the variable to be replaced must be given as follows: {DATE|yyyy|+1,y}. This means the result will be 2017, one year added to 2016.

SydroCmd –replace d:\temp\abc.txt DATE 201612050000 d:\temp\abcnew.txt

Example 2: with date information using Now

In this example the first argument is the keyword DATE indicating that date information is used. If this string is found it will be replaced by the date given in the next argument (here the keyword Now). In the file abc.txt the variable to be replaced must be given as follows: {DATE|yyyyMMdd|+1,M}. This means the result will be the current date plus one month.

SydroCmd –replace d:\temp\abc.txt DATE Now d:\temp\abcnew.txt

Zip

Compress files to a zip file.

Argument	Description
Key	-zip
1	source directory
2	zip filename
3	-pattern or –list
4	the pattern or a comma-separated list

Example 1: Compresses all files in directory d:\temp\ with the extension *.txt to the file myfile.zip

SydroCmd  –zip d:\temp\ myfile.zip –pattern *.txt

Example 2: Compresses a list of files in directory d:\temp\ with the extension *.txt to the file myzipfile.zip

SydroCmd -zip  d:\temp\ myzipfile.zip -list d:\mylist\file1.txt "d:\many files\newfile.doc"

UnZip

Unzips files from a zip file.

Argument	Description
Key	-unzip
1	source directory
2	source zip filename
3	-pattern or -list
4	the pattern or a comma-separated list

Example 1: Unzips all files in directory d:\temp\ and zipfile myfile.zip with the pattern *.txt to d:\

SydroCmd -unzip d:\ d:\temp\myfile.zip -pattern *.txt

Example 2: Unzips a selection of files from d:\temp\ and myzipfile to d:\

SydroCmd -unzip d:\ d:\temp\myzipfile.zip -list d:\mylist\file1.txt "d:\any directory\newfile.doc"

Example 3: Unzips all files in the zipfile from d:\temp\ and myzipfile to d:\

SydroCmd -unzip d:\ d:\temp\myzipfile.zip –pattern *.*
