sed by nature can not read and write to the same file, in fact the main idea of sed is not to change source files, I'd rather write to a temporary file and then change anything I want.
cheers

Hello
I need to run some sed commands but it involves "/" in the substitute or delete, any ideas how I get round the problem.
Example:
cat file1.txt | sed -e '/</Header>/d' > file2.txt
This errors due to the forward slash before the Header text.

zipnote
zipnote(1) General Commands Manual zipnote(1)
NAME
zipnote - write the comments in zipfile to stdout, edit comments and rename files in zipfile
SYNOPSIS
zipnote [-w] [-b path] [-h] [-v] [-L] zipfile
ARGUMENTS
zipfile Zipfile to read comments from or edit.
OPTIONS
-w Write comments to a zipfile from stdin (see below).
-b path
Use path for the temporary zip file.
-h Show a short help.
-v Show version information.
-L Show software license.
DESCRIPTION
zipnote writes the comments in a zipfile to stdout. This is the default mode. A second mode allows updating the comments in a zipfile as
well as allows changing the names of the files in the zipfile. These modes are described below.
EXAMPLES
To write all comments in a zipfile to stdout use for example
zipnote foo.zip > foo.tmp
This writes all comments in the zipfile foo.zip to the file foo.tmp in a specific format.
If desired, this file can then be edited to change the comments and then used to update the zipfile.
zipnote -w foo.zip < foo.tmp
The names of the files in the zipfile can also be changed in this way. This is done by following lines like
"@ name"
in the created temporary file (called foo.tmp here) with lines like
"@=newname"
and then using the -w option as above.
BUGS
The temporary file format is rather specific and zipnote is rather picky about it. It should be easier to change file names in a script.
Does not yet support large (> 2 GB) or split archives.
