Using sed

By default, sed reads newline-separated input. This command will remove everything before the last \r on a line:

sed 's/.*\r//'

For example:

$ echo $'line1\n\hi\rhello\rworld' | sed 's/.*\r//'
line1
world

Using awk

Similarly, this removes everything before the last \r on a newline-separated line:

awk -F'\r' '{print $NF}'

For example:

$ echo $'line1\n\hi\rhello\rworld' | awk -F'\r' '{print $NF}'
line1
world

Using sed

By default, sed reads newline-separated input. This command will remove everything before the last \r on a line:

sed 's/.*\r//'

For example:

$ echo $'line1\n\hi\rhello\rworld' | sed 's/.*\r//'
line1
world

To use this with tee, we can use process substitution:

echo $'line1\n\hi\rhello\rworld' | tee >(sed 's/.*\r//' >Outfile)

Under bash, the construct >(...) is called process substitution. It runs the commands in the parens and puts them in a file-like object. tee write to the file-like object and the commands process the input.

Using awk

Similarly, this removes everything before the last \r on a newline-separated line:

awk -F'\r' '{print $NF}'

The option -F'\r' sets the field separator to a carriage return. Consequently, we only want to print the last field, $NF, on each newline-separated line. Thus, print $NF.

For example:

$ echo $'line1\n\hi\rhello\rworld' | awk -F'\r' '{print $NF}'
line1
world

To use this with tee:

echo $'line1\n\hi\rhello\rworld' | tee >(awk -F'\r' '{print $NF}' >Outfile)
