Remove lines that contain a specific pattern($1) from file($2).

The -i option in sed allows in-place editing of the input file. Replace myexpression with any regular expression. /expr/d syntax means if the expression matches then delete the line. You can reverse the functionality to keep matching lines only by using: sed -i -n '/myexpression/p' /path/to/file.txt
This is sample output - yours may be different.

sed -i '/myexpression/d' /path/to/file.txt

Both view and pipe the file without saving to disk

This is a cool trick to view the contents of the file on /dev/pts/0 (or whatever terminal you're using), and also send the contents of that file to another program by way of an unnamed pipe. All the while, you've not bothered saving any extra data to disk, like you might be tempted to do with sed or grep to filter output.
This is sample output - yours may be different.

cat /path/to/some/file.txt | tee /dev/pts/0 | wc -l

Indicates the position of my monitor buttons

I often need to change the brightness of my monitor. The symbols of the sensor buttons are not illuminated and on a black background .... invisible! Now i use osd_cat instead of a torch ;-)

Put uppercase letters in curly brackets in a BibTeX database

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===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.

Open in TextMate Sidebar files (recursively) with names matching REGEX_A and not matching REGEX_B

This does the following: 1 - Search recursively for files whose names match REGEX_A 2 - From this list exclude files whose names match REGEX_B 3 - Open this as a group in textmate (in the sidebar) And now you can use Command+Shift+F to use textmate own find and replace on this particular group of files. For advanced regex in the first expression you can use -regextype posix-egrep like this: mate - `find * -type f -regextype posix-egrep -regex 'REGEX_A' | grep -v -E 'REGEX_B'` Warning: this is not ment to open files or folders with space os special characters in the filename. If anyone knows a solution to that, tell me so I can fix the line.

Get AWS temporary credentials ready to export based on a MFA virtual appliance

You might want to secure your AWS operations requiring to use a MFA token. But then to use API or tools, you need to pass credentials generated with a MFA token. This commands asks you for the MFA code and retrieves these credentials using AWS Cli. To print the exports, you can use: `awk '{ print "export AWS_ACCESS_KEY_ID=\"" $1 "\"\n" "export AWS_SECRET_ACCESS_KEY=\"" $2 "\"\n" "export AWS_SESSION_TOKEN=\"" $3 "\"" }'` You must adapt the command line to include: * $MFA_IDis ARN of the virtual MFA or serial number of the physical one * TTL for the credentials
