|--error=code (-x code)||Ordinarily, edinplace attempts to exit with the same status as command. However, if edinplace encounters some fatal error (such as being unable to execute command), it will exit with status code. The default value is 1. The range of valid exit codes is 1-255, inclusive.|
|--file=file (-f file)||Specifies that file should be edited. Otherwise, edinplace will edit its standard input (which must be opened for both reading and writing).|
|--skipfrom||Skip the first line of the file if it starts From . If edinplace is run without a command, positions the file offset at the start of the second line of the file. If edinplace is run with a command, then the first line of the file is neither fed to the command, nor overwritten. This option is useful for running edinplace over mail files, which sometimes start with a From line specifying the envelope sender of the message. Since From is not part of the message header, just a Unix convention, some programs are confused by the presence of that line. Note that if you specify a command, then edinplace resets the file offset to 0 upon exiting, even if the --skipfrom option was present.|
The following command prepends the string ORIGINAL: to the beginning of each line in text file message:
edinplace -f message sed -e s/^/ORIGINAL: /
The following command runs the spamassassin mail filter program on a mail message stored in file message, replacing the contents of message with spamassassins annotated output, and exiting with code 100 if spamassassin thinks the message is spam. If edinplace encounters any fatal errors, it will exit with code 111.
edinplace -x 111 -f message spamassassin -e 100
(spamassassin reads a mail message on standard input and outputs an annotated copy of the message including information about whether or not the message is likely to be spam and why. The -e option to spamassassin specifies what exit status spamassassin should use if the message appears to be spam; edinplace will use the same exit code as the program it has run.)
To run spamassassin on incoming mail before accepting the mail from the remote client, place the following line in an appropriate Mail Avenger rcpt file as the last command executed:
bodytest edinplace -x 111 spamassassin -e 100

edinplace does not make a copy of the file being edited, but rather overwrites the file as it is being processed. At any point where command has produced more output than it has consumed input from the file, edinplace buffers the difference in memory. Thus, a command that outputs large amounts of data before reading the input file can run edinplace out of memory. (A program that outputs data as it reads even a very large file should be fine, however.)
If command crashes or malfunctions for any reason, you will likely lose the input file, since edinplace will view this as a program that simply outputs the empty file.
