/ No end of line marker at the end of the file: # signs after the character indicate line numbers in the second file. # signs before the character indicate line numbers in the first file. # signs separated by commas indicate a line range. #,#c#,# - change lines from line # -> # in file1 into the lines in file2 at line # -> # #,#d# - delete lines from line # -> # in file 1 from file2 at line # #a#,# - add lines from line # in file1 into file2 at lines #-># " " line prefix for lines from the second file The Unix output format is constructed in the following way: Unix output type is derived from the UNIX-based diff command output format. line only when the distance to the next difference string is larger than the number of context lines. Unified format produces a new unified difference string (. format:context repeats identical context lines between the difference strings, but /format:unified doesn't. Unified format is derived from the UNIX-based diff -u output format. SS_Unix is similar to the /format:unix output format, but /format:ss_unix includes context lines and /format:unix doesn't. SS_SideBySide is the default side-by-side output format for Visual SourceSafe. For more information, see Diff (command line). SS is the default difference output format for Visual SourceSafe. No special handing for a missing end of line marker at the end of the file is provided. RCS format is similar to /format:unix, except context lines aren't supplied. This format is derived from the UNIX-based diff -c output format. By default, diffmerge.exe is launched.īrief format prints whether the files being compared differ.Ĭontext format provides lines of context for the differences in the files. Visual format type opens an external difference application. The following output types are available: The format parameter, used with the /format option, specifies many different output formats. If you specify a range of versions such as /version:C1~C4, the versions of the file at the two endpoints of the range are compared.įor more information on how to use the tf command-line utility, see Use Team Foundation version control commands. If you include a versionspec in your itemspec, such as tf difference header.h LBeta1, TFVC compares that version to your current workspace version on disk. For example, tf difference header.h compares the current version of header.h to the version upon which header.h is based. If you don't provide a versionspec, your current workspace version of the item is compared to the base workspace version, by default. If you pass only one itemspec to the difference command: Instead of using the /version flag, you can specify versions by appending a semicolon and version specifier to the end of each file name. If you specify two file names, the two files are compared. For more information about how TFVC differentiates between and treats files of different types, see Managing file types. When you pass one or more binary files to the difference command, TFVC indicates whether differences exist between it and the item to which it's being compared. If you want to compare two files whose encodings aren't the same, you can temporarily mask or override the encoding property for a file by using the /type option.īinary files can be compared but can't be merged. Text files can be merged and compared, side by side and line by line, as long as both files have the same encoding. You can use the difference command to compare both versioned and non-versioned files. One, some, or all the items in a shelveset on the Azure DevOps server. Two different files or two versions of the same file. You can use the difference command to compare and if possible display differences between: You can type tf diff or tf difference at the command line to run this command. For more information, see Default TFVC permissions. To use the difference command, you must have the Read permission for all specified items set to Allow. The Team Foundation Version Control (TFVC) difference command compares, and if possible displays, differences between two files, files in two folders, or a shelveset and a local or a server file.
