  • If you've ever wanted to change a text files contents without having to create an intermediate file. This is it. Ex is a part of vim. The command as given will delete ALL lines containing "delete this line" from the file. More Examples: print '%s/'this is a line'/'that is not the same line'/g\nwq' | ex file.txt will substitute the first string with the second string. print '3a\n'Inserted Line'\n.\n\nwq' | ex file.txt will insert the given line after line 3. CAVEAT, Some distro's like the print command, others like echo with this command. Also note there are NO error messages on failure, at least that I've ever seen. Ex can also be quite fussy as to how it takes strings, parameters, etc... I use at&t's ksh syntax may very with other shells.

  • Strips comments from at least bash and php scripts. Normal # and // as well as php block comments removes all of the: empty/blank lines lines beginning with # lines beginning with // lines beginning with /* lines beginning with a space and then * lines beginning with */ It also deletes the lines if there's whitespace before any of the above. Add an alias to use in .bashrc like this: alias stripcomments="sed -e '/^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' -e '/^$/d' -e '/^\/\/.*/d' -e '/^\/\*/d;/^ \* /d;/^ \*\//d'"

  • rsync'ing an empty directory over a directory to be deleted recursively is much faster than using rm -rf, for various reasons. Relevant only for directories with really a lot of files.

    blank=$(mktemp -d); rsync --delete "$blank/" "bigdir/"; rmdir "$blank"

  • The shortest and most complete comment/blank line remover... Any line where the first non-whitespace character is # (ie, indented # comments), and all null and blank lines are removed. Use the alias as a filter: noc /etc/hosts or grep server /etc/hosts | noc Change to nawk depending awk versions. Show Sample Output

    alias noc="awk 'NF && ! /^[[:space:]]*#/'"
