rx
Regexp pattern matching for file system objects (eg '.*.txt')
Returns a list of files and directories that match a regexp pattern.
Output is a JSON list.
rx: pattern -> <stdout>
!rx: pattern -> <stdout>
Inline regex file matching:
cat: @{ rx: '.*\.txt' }
Writing a list of files to disk:
rx: '.*\.go' -> > filelist.txt
Checking if files exist:
if { rx: somefiles.* } then {
# files exist
}
Checking if files do not exist:
!if { rx: somefiles.* } then {
# files do not exist
}
Return all files apart from text files:
!g: '\.txt$'
Unlike globbing (g
) which can traverse directories (eg g: /path/*
), rx
is only designed to match file system objects in the current working directory.
rx
uses Go (lang)'s standard regexp engine.
If you want to exclude any matches based on wildcards, rather than include them, then you can use the bang prefix. eg
» rx: READ*
[
"README.html"
]
murex-dev» !rx: .*
Error in `!rx` (1,1): No data returned.
