Help with an IF and SED to replace \n

  • 772

I have a filename variable that sometimes gets set as:

attachment; 
JobRunStatisticsReport_20150122.zip

In the File Manager window, it looks like this:

enter image description here

I need help coming up with an IF statement that says:

IF $filename contains 'attachment; \n' then

and then help with a SED that looks for that new line character (\n) and replaces that and everything before it with nothing.

Can anyone lend a quick hand please?

command-line

  1. Your filename actually contains both a carriage return and a newline. bash parameter expansion can handle this:

    $ filename=$'attachment;\r\nJobRunStatisticsReport_20150122.zip'
$ echo "$filename"
attachment;
JobRunStatisticsReport_20150122.zip
$ shopt -s extglob
$ echo "${filename##attachment;*([[:space:]])}"
JobRunStatisticsReport_20150122.zip

    Does not affect "normal" filenames:

    $ filename="no attachment here"
$ echo "${filename##attachment;*([[:space:]])}"
no attachment here
