.TH 7zr 1 "March 6th, 2016" "7-Zip" .SH NAME 7zr \- A file archiver with high compression ratio format .SH SYNOPSIS .B 7zr .B .RB [ "... ]" .B .RB [ "... ]" .RB [ <@listfiles> "... ]" .PP .SH DESCRIPTION 7-Zip is a file archiver supporting 7z (that implements LZMA compression algorithm featuring very high compression ratio), LZMA2, XZ, ZIP, Zip64, CAB, RAR (if the non-free p7zip-rar package is installed), ARJ, GZIP, BZIP2, TAR, CPIO, RPM, ISO, most filesystem images and DEB formats. Compression ratio in the new 7z format is 30-50% better than ratio in ZIP format. .PP .B 7zr is a stand-alone executable. .B 7zr is a "light-version" of .BR 7za (1). .B 7zr handles password-less archives in the 7z, LZMA2, and XZ formats only. .SH COMMANDS .TP .B a Add files to archive .TP .B b Benchmark .TP .B d Delete files from archive .TP .B e Extract files from archive (without using directory names) .TP .B h Calculate hash values for files .TP .B i Show information about supported formats .TP .B l List contents of archive .TP .B rn Rename files in archive .TP .B t Test integrity of archive .TP .B u Update files to archive .TP .B x eXtract files with full paths .PP .SH SWITCHES .TP .B \-\- Stop switches parsing .TP .B \-ai[r[-|0]]{@listfile|!wildcard} Include archives .TP .B \-ax[r[-|0]]{@listfile|!wildcard} Exclude archives .TP .B \-ao{a|s|t|u} Set Overwrite mode .TP .B \-an Disable archive_name field .TP .B -bb[0-3] Set output log level .TP .B \-bd Disable progress indicator .TP .B \-bs{o|e|p}{0|1|2} Set output stream for output/error/progress line .TP .B \-bt Show execution time statistics .TP .B \-i[r[\-|0]]{@listfile|!wildcard} Include filenames .TP .B \-m{Parameters} Set Compression Method (see /usr/share/doc/p7zip/DOC/MANUAL/cmdline/switches/method.htm from the p7zip-full package for a list of methods) .TP .B \-o{Directory} Set Output directory .TP .B \-r[\-|0] Recurse subdirectories (CAUTION: this flag does not do what you think, avoid using it) .TP .B \-sa{a|e|s} Set archive name mode .TP .B \-scc{UTF\-8|WIN|DOS} Set charset for for console input/output .TP .B \-scs{UTF\-8|UTF\-16LE|UTF\-16BE|WIN|DOS|{id}} Set charset for list files .TP .B \-scrc[CRC32|CRC64|SHA1|SHA256|*] Set hash function for x, e, h commands .TP .B \-sdel Delete files after compression .TP .B \-seml[.] Send archive by email .TP .B \-sfx[{name}] Create SFX archive .TP .B \-si[{name}] Read data from stdin (e.g. tar cf \- directory | 7zr a \-si directory.tar.7z) .TP .B \-slp Set Large Pages mode .TP .B \-slt Show technical information for l (List) command .TP .B \-snh Store hard links as links .TP .B \-snl Store symbolic links as links .TP .B \-sni Store NT security information .TP .B \-sns[\-] Store NTFS alternate streams .TP .B \-sfx[{name}] Create SFX archive .TP .B \-so Write data to stdout (e.g. 7zr x \-so directory.tar.7z | tar xf \-) .TP .B \-spd Disable wildcard matching for file names .TP .B \-spe Eliminate duplication of root folder for extract command .TP .B \-spf Use fully qualified file paths .TP .B \-ssc[\-] Set sensitive case mode .TP .B \-ssw Compress shared files .TP .B \-stl Set archive timestamp from the most recently modified file .TP .B \-stm{HexMask} Set CPU thread affinity mask (hexadecimal number) .TP .B \-stx{Type} Exclude archive type .TP .B \-t{Type} Set type of archive .TP .B \-u[-][p#][q#][r#][x#][y#][z#][!newArchiveName] Update options .TP .B \-v{Size}[b|k|m|g] Create volumes .TP .B \-w[path] Set working directory. Empty path means a temporary directory .TP .B \-x[r[\-|0]]]{@listfile|!wildcard} Exclude filenames .TP .B \-y Assume Yes on all queries .PP .SH DIAGNOSTICS 7-Zip returns the following exit codes: .RS .IP 0 Normal (no errors or warnings detected) .IP 1 Warning (Non fatal error(s)). For example, some files cannot be read during compressing, so they were not compressed .IP 2 Fatal error .IP 7 Bad command line parameters .IP 8 Not enough memory for operation .IP 255 User stopped the process with control-C (or similar) .SH Backup and limitations DO NOT USE the 7-zip format for backup purpose on Linux/Unix because : \- 7-zip does not store the owner/group of the file. .LP On Linux/Unix, in order to backup directories you must use tar : \- to backup a directory : tar cf \- directory | 7zr a \-si directory.tar.7z \- to restore your backup : 7zr x \-so directory.tar.7z | tar xf \- If you want to send files and directories (not the owner of file) to others Unix/MacOS/Windows users, you can use the 7-zip format. example : 7zr a directory.7z directory .LP Do not use "\-r" because this flag does not do what you think. .LP Do not use directory/* because of ".*" files (example : "directory/*" does not match "directory/.profile") .SH EXAMPLE 1 .TP .B 7zr a \-t7z \-m0=lzma \-mx=9 \-mfb=64 \-md=32m \-ms=on archive.7z dir1 adds all files from directory "dir1" to archive archive.7z using "ultra settings" .TP .B \-t7z 7z archive .TP .B \-m0=lzma lzma method .TP .B \-mx=9 level of compression = 9 (Ultra) .TP .B \-mfb=64 number of fast bytes for LZMA = 64 .TP .B \-md=32m dictionary size = 32 megabytes .TP .B \-ms=on solid archive = on .SH EXAMPLE 2 .TP .B 7zr a \-sfx archive.exe dir1 add all files from directory "dir1" to SFX archive archive.exe (Remark : SFX archive MUST end with ".exe") .SH "SEE ALSO" .BR 7za (1), .BR 7z (1), .BR p7zip (1), .BR bzip2 (1), .BR gzip (1), .BR zip(1), .PP .SH "HTML Documentation" /usr/share/doc/p7zip/DOC/MANUAL/start.htm (avabilable when the p7zip-full package is installed) .SH AUTHOR .TP Written for Debian by Mohammed Adnene Trojette.
