Hi,

I've been searching for a quick way to do this with sed, but to no avail.

I have a file containing a long series of (windows) file paths that are separated by the pattern '@'. I would like to extract each file path so that I can later assign a variable to each path.

Here is the file:

C:\Documents and Settings\My Documents\MATLAB@C:\Documents and Settings\My Documents\MATLAB\a.zip@C:\Documents and Settings\My Documents\MATLAB\f.bhdr@C:\Documents and Settings\My Documents\MATLAB\f_000.bshort@C:\Documents and Settings\My Documents\MATLAB\f_000.hdr@C:\Documents and Settings\My Documents\MATLAB\f_004.bshort@C:\Documents and Settings\My Documents\MATLAB\f_004.hdr@
C:\Documents and Settings\My Documents\MATLAB@C:\Documents and Settings\My Documents\MATLAB\test.nii.gz@C:\Documents and Settings\My Documents\MATLAB\test.zip@C:\Documents and Settings\My Documents\MATLAB\test2.txt@C:\Documents and Settings\My Documents\MATLAB\tmp.tiff@

And I would like the output to be:

C:\Documents and Settings\My Documents\MATLAB
C:\Documents and Settings\My Documents\MATLAB\a.zip
C:\Documents and Settings\My Documents\MATLAB\f.bhdr
C:\Documents and Settings\My Documents\MATLAB\f_000.bshort
C:\Documents and Settings\My Documents\MATLAB\f_000.hdr
C:\Documents and Settings\My Documents\MATLAB\f_004.bshort
C:\Documents and Settings\My Documents\MATLAB\f_004.hdr
C:\Documents and Settings\My Documents\MATLAB
C:\Documents and Settings\My Documents\MATLAB\test.nii.gz
C:\Documents and Settings\My Documents\MATLAB\test.zip
C:\Documents and Settings\My Documents\MATLAB\test2.txt
C:\Documents and Settings\My Documents\MATLAB\tmp.tiff

I can sort-of get there with something like:

sed 's,^\(.*@\)\?\([^@]*\),\1,'

in a loop or something like that, but I was hoping for a simpler (a one-liner maybe?) or a more elegant solution. If anyone can help, I would greatly appreciate it. Thanks in advance!

many ways to achive this

cat filename | tr "@" "\n"

or

awk 'BEGIN{RS="@"}{print}' filename

or

sed '/\@/s//\n/g' filename
