And when I do:



less -R demo


I get no colors:

  • Note that an actual escape character (U+1B) would be represented as ESC in inverse colors, if you ran less demo, without -R.

You need to put the actual escape code in the file. One way to do this would be:



echo -e "33[31mException log" > file.txt


Then less -R file.txt should be able to interpret the color code.

    These characters are not a colour code sequence, but they are the sequence to tell some tools/programming-languages to create the desired character sequence.



    e.g.



    echo -e "33[31mException log"

                      5 2 In restoring a database from a pg_dump , a number of errors are being generated and the whole table is subsequently being ignored. An example: ERROR: insert or update on table "channelproducts" violates foreign key constraint "fk_rails_dfaae373a5" DETAIL: Key (channel_id)=(1) is not present in table "channels". Interestingly enough, I've noted that all these instances are popping up because of the sequence of loading. channels is after channelproducts both alphabetically and in the file and thus I can understand why postgres complains about having to create a child without a parent. caveat: the foreign key is being generated automatically by rails 4.2: I could remove the problem at the source but that still does not really solve the problem... version: PostgreSQL
