# This is a script to generate “awkward” files and directories that the
|
||
# testing scripts use as integration test cases.
|
||
#
|
||
# Tests like these verify that exa is doing the right thing at every step,
|
||
# from command-line parsing to colourising the output properly -- especially
|
||
# on multiple or weird platforms!
|
||
#
|
||
# Examples of the things it generates are:
|
||
# - files with newlines in their name
|
||
# - files with invalid UTF-8 in their name
|
||
# - directories you aren’t allowed to open
|
||
# - files with users and groups that don’t exist
|
||
# - directories you aren’t allowed to read the xattrs for
|
||
|
