| Linux / Unix Command: sdiff |
NAME
sdiff - find differences between two files and merge interactivelySYNOPSIS
sdiff -o outfile [options] from-file to-fileDESCRIPTION
The sdiff command merges two files and interactively outputs the results to outfile.If from-file is a directory and to-file is not, sdiff compares the file in from-file whose file name is that of to-file, and vice versa. from-file and to-file may not both be directories.
sdiff options begin with -, so normally from-file and to-file may not begin with -. However, -- as an argument by itself treats the remaining arguments as file names even if they begin with -. You may not use - as an input file.
sdiff without -o (or --output) produces a side-by-side difference. This usage is obsolete; use diff --side-by-side instead.
Options
Below is a summary of all of the options that GNU sdiff accepts. Each option has two equivalent names, one of which is a single letter preceded by -, and the other of which is a long name preceded by --. Multiple single letter options (unless they take an argument) can be combined into a single command line argument. Long named options can be abbreviated to any unique prefix of their name.- -a
- Treat all files as text and compare them line-by-line, even if they do not appear to be text.
- -b
- Ignore changes in amount of white space.
- -B
- Ignore changes that just insert or delete blank lines.
- -d
- Change the algorithm to perhaps find a smaller set of changes. This makes sdiff slower (sometimes much slower).
- -H
- Use heuristics to speed handling of large files that have numerous scattered small changes.
- --expand-tabs
- Expand tabs to spaces in the output, to preserve the alignment of tabs in the input files.
- -i
- Ignore changes in case; consider upper- and lower-case to be the same.
- -I regexp
- Ignore changes that just insert or delete lines that match regexp.
- --ignore-all-space
- Ignore white space when comparing lines.
- --ignore-blank-lines
- Ignore changes that just insert or delete blank lines.
- --ignore-case
- Ignore changes in case; consider upper- and lower-case to be the same.
- --ignore-matching-lines=regexp
- Ignore changes that just insert or delete lines that match regexp.
- --ignore-space-change
- Ignore changes in amount of white space.
- -l
-
- --left-column
- Print only the left column of two common lines.
- --minimal
- Change the algorithm to perhaps find a smaller set of changes. This makes sdiff slower (sometimes much slower).
- -o file
-
- --output=file
- Put merged output into file. This option is required for merging.
- -s
-
- --suppress-common-lines
- Do not print common lines.
- --speed-large-files
- Use heuristics to speed handling of large files that have numerous scattered small changes.
- -t
- Expand tabs to spaces in the output, to preserve the alignment of tabs in the input files.
- --text
- Treat all files as text and compare them line-by-line, even if they do not appear to be text.
- -v
-
- --version
- Output the version number of sdiff.
- -w columns
-
- --width=columns
- Use an output width of columns. Note that for historical reasons, this option is -W in diff, -w in sdiff.
- -W
- Ignore horizontal white space when comparing lines. Note that for historical reasons, this option is -w in diff, -W in sdiff.
