Simple bash script to remove tqdm output from logfile

striptqdm.sh

#!/bin/bash

# Intended usage:
# - You run a super long script with fancy tqdm progress bars in a remote server as usual:
#
#   nohup python super_long_script.py > super_long.log &

#   # monitor as long as you want
#   tail -f super_long.log

# ... some time later

# - Inspecting the log with a regular cat super_long.log works perfectly fine, the problem comes when you `less` it to
#   inspect more carefully... less renders tqdm nasty, using this script fixes that
#
#   cat super_long.log | striptqdm | less

#   or simply
#   striptqdm super_long.log | less

# relaxed version, may fail for certain strings:
# sed -r '/^ *[0123456789]+%.*$/d'
if [[ ! -t 0 && ! -p /dev/stdin ]]; then
        cat | tr '\r' '\n' | sed -r '/^.*[0123456789]+%.*$/d' | sed -e '/^ *$/d'
else
        cat $@ | tr '\r' '\n' | sed -r '/^.*[0123456789]+%.*$/d' | sed -e '/^ *$/d'
