Commands tagged BibTeX (2)

  • It is often recommended to enclose capital letters in a BibTeX file in braces, so the letters will not be transformed to lower case, when imported from LaTeX. This is an attempt to apply this rule to a BibTeX database file. DO NOT USE sed '...' input.bib > input.bib as it will empty the file! How it works: /^\s*[^@%]/ Apply the search-and-replace rule to lines that start (^) with zero or more white spaces (\s*), followed by any character ([...]) that is *NOT* a "@" or a "%" (^@%). s=<some stuff>=<other stuff>=g Search (s) for some stuff and replace by other stuff. Do that globally (g) for all matches in each processed line. \([A-Z][A-Z]*\)\([^}A-Z]\|},$\) Matches at least one uppercase letter ([A-Z][A-Z]*) followed by a character that is EITHER not "}" and not a capital letter ([^}A-Z]) OR (|) it actually IS a "}", which is followed by "," at the end of the line ($). Putting regular expressions in escaped parentheses (\( and \), respectively) allows to dereference the matched string later. {\1}\2 Replace the matched string by "{", followed by part 1 of the matched string (\1), followed by "}", followed by the second part of the matched string (\2). I tried this with GNU sed, only, version 4.2.1. Show Sample Output

Recover deleted Binary files
The above command assumes the lost data is on /dev/sda and you previously issued the following command to mount _another_ disk or partition (/dev/sdb1) on /recovery $sudo mount /dev/sdb1 /recovery If you don't do this, the data could be overwrited! foremost is a very powerful carving tool. By default foremost recovers all known file types. If you want to reduce the amount of files that are recovered you can specify the file type you are looking for. Read the man page to know the available file types. i.e to recover JPEG pictures append to foremost the switch -tjpg
