So, I always am using some command line shortcuts to do various tasks, and often have to look up the tricks every time I need to do something remotely fancy. Here are some of my most-used helpful hints:
- To remove the leading spaces and tabs from each line of text on standard in (so use with a pipe for the input), this sed command will work well:
sed -e 's/^[ \t]*//'
- Reformatting XML/HTML files so that line returns inside tags are removed:
xmllint --format --noblanks infile.xml > outfile.xml
