Hi,
Newbie here. Need to convert a txt file to .csv format. There's no character to replace so not sure if I can use sed :confused: . The comma is to be inserted after every certain number of characters in each line...
Help!
Thanks. (4 Replies)

sed is not applying /d "delete line" option when I also include match word options \< and \>
examples...
echo cat | sed '/\<cat\>/d'
will return cat for some reason
echo cat | sed "/\<cat\>/d"
will also still return cat.
Of course I can just run this... echo cat | sed '/cat/d' and... (1 Reply)

FCALL(3) Library Functions Manual FCALL(3)NAME
fcall - recreate packet delimiters
SYNOPSIS
Fctlfd = open(".../ctl", ORDWR);
Fwrite(ctlfd, "push fcall", 10);
DESCRIPTION
Fcall is a stream module (see stream(3)) that can be pushed onto a connection to a 9P file server. The function of the module is to recre-
ate packet delimiters lost in transmission. The 9P protocol demands that network connections preserve delimiters between messages written
to the file server. Stream based protocols, like TCP, are unable to preserve delimiters. The delimiters must be recreated by the receiver
before a packet is read by a file system.
Fcall examines a data stream and identifies 9P messages from their type. The length of the message is computed from the header. Data is
collected and buffered by the stream module until an entire 9P message has been assembled. A single message is then delimited and sent
upstream to be read by a file server.
