[ 3 ] [ 4 ] [ 5 ] The user can start a bisection session with a specified range of revisions from which the revision control system proposes a revision to test, the user tells the system whether the revision tested as "good" or "bad", and the ...
[9] This is implemented e.g. in the Git version control system as the command git bisect, which uses the above algorithm to determine which commit introduced a particular bug. Record and replay debugging is the technique of creating a program execution recording (e.g. using Mozilla's free rr debugging tool; enabling reversible debugging ...
Line continuation – escapes a newline to continue a statement on the next line Some languages define a special character as a terminator while some, called line-oriented , rely on the newline . Typically, a line-oriented language includes a line continuation feature whereas other languages have no need for line continuation since newline is ...
unix2dos (sometimes named todos or u2d) is a tool to convert line breaks in a text file from Unix format (Line feed) to DOS format (carriage return + Line feed) and vice versa. . When invoked as unix2dos the program will convert a Unix text file to DOS format, when invoked as dos2unix it will convert a DOS text file to Unix for
echo began within Multics.After it was programmed in C by Doug McIlroy as a "finger exercise" and proved to be useful, it became part of Version 2 Unix. echo -n in Version 7 replaced prompt, (which behaved like echo but without terminating its output with a line delimiter).
Git – a distributed version control system. In the project's initial README file, Linus Torvalds wrote that "'git' can mean anything, depending on your mood", and offers several definitions: [23] A random three-letter combination which is pronounceable and not a preexisting Unix command; British English slang, meaning a stupid or contemptible ...
On Twitter and some instant messaging services, there is a limit to the number of characters a message can carry – however, Twitter now shortens links automatically using its own URL shortening service, t.co, so there is no need to use a separate URL shortening service just to shorten URLs in a tweet. On other such services, using a URL ...
The Korn Shell was introduced at around the same time as was the Bourne shell. It provides some features borrowed from Python and Ruby, such as associative arrays and floating point arithmetic, and aims to support the new POSIX standard. [13]
