filefilter is a tool which applies and rewrites a filter to a file.
I was tired from writing a shell script each time.
It is a tool which applies a filter to the specified file.
This is effective when rewriting a lot of file.
FILTERDIR="${HOME}/filter"
cat example.txt \
| ${FILTERDIR}/filter1 \
| ${FILTERDIR}/filter2 \
| ${FILTERDIR}/filter3 \
> example.txt.new
mv example.txt.new example.txt
export FF_FILTERDIR="${HOME}/filter"
python3 filefilter.py \
-f filter1 filter2 filter3 \
-i example.txt
Python 3.x
filefilter.py [-h] -f FILTER [FILTER ...] [-i INPUT [INPUT ...]]
[--caller CALLER] [--filterdir FILTERDIR]
[--workdir WORKDIR]
| Name | Usage | Default |
|---|---|---|
| FF_CALLER | The program for calling a filter (ex. /usr/bin/env) | None |
| FF_FILTERDIR | The search path of a filter | None |
| FF_WORKDIR | The directory which creates a file temporarily | . |
- FF_FILTERDIR is a PATH environment variable at the time of a filter call.
- set up "FF_CALLER=/usr/bin/env", when you use it by MINGW.
- A temporary directory(filefilter_***) is not deleted when an error occurs.
