Top Forums Shell Programming and Scripting Using sed command to replace "|" with ^ for all *.dat files in a folder not working Post 303022995 by Don Cragun on Monday 10th of September 2018 09:36:42 AM
What operating system and shell are you using?

Note that sed is only defined to work on text files and data files with the filename extension .dat are frequently binary files that do not meet the requirements of text files!

In what way is it "not working"?

Does it produce any diagnostic messages?

Does it just work on the first named file operand?

Is it using your editing command as a filename extension for your backup files instead of as an editing command?

If you're on a system using a BSD-based sed, does the command:
Code:
sed -i '' 's/"|"/^/g' *.dat

come closer to working for you?

rmm(1)							      General Commands Manual							    rmm(1)

NAME
rmm - remove messages (only available within the message handling system, mh) SYNOPSIS
rmm [+folder] [msgs] [-help] OPTIONS
Prints a list of the valid options to this command. The default settings for this command are: +folder defaults to the current folder msgs defaults to the current message DESCRIPTION
The rmm command deletes the current message from the current folder. You can specify messages and folders other than the current ones by using the +folder and msgs arguments. The current message is not changed by rmm, so a next will advance to the next message in the folder as expected. If you have defined a component rmmproc: in your file, then instead of simply renaming the message file, rmm will call the named program to delete the file. The rmm command removes messages by renaming the message files with a preceding comma. Many sites consider files that start with a comma to be a temporary backup, and arrange for cron(8) to remove such files once a day. PROFILE COMPONENTS
Path: To determine your Mail directory rmmproc: Program to delete the message FILES
The user profile. SEE ALSO
