"Linux" unzip command, remember the problem encountered

Recently in the Boss System Cloud Platform deployment script, the tune-up found a problem in the shell script, the following records

A place to indicate whether to overwrite

[[email protected]test]# unzip/home/redis/test/main-d-1544-160316.zip-d/home/redis/test/staribossarchive:/home/redis/test/ Main-d-1544-160316.zipreplace/home/redis/test/stariboss/dbpasswordencryption.bat? [Y]es, [N]o, [A]ll, [N]one, [r]ename: Query the Unzip command, through-O to solve the problem,-o so that the decompression without first asking the user, unzip after the implementation of overwriting the original file.

Unzip-o/home/redis/test/main-d-1544-160316.zip-d/home/redis/test/stariboss an OU

Realize that the shell script should pay attention to the exception problem, because the execution of the script may be adjusted, so that some exception files exist, to be processed when writing, for example, using-o processing when extracting, or in the footsteps of using RM in advance to remove some temporary files, to avoid because of script errors, not deleted, Follow up again because these exception files or data cause other problems UNZIP instruction summary

command name : Unzip

function Description : Unzip the zip file

Syntax: Unzip [-cflptuvz][-agcjlmnoqsvx][-p < password >][.zip file] [file][-d < directory >][-x < file;] or unzip [-z]

Parameters

-C Displays the extracted results to the screen and converts the characters appropriately.

-F Updates an existing file.

-L Displays the files contained within the compressed file.

-P, similar to the-c parameter, displays the results of the decompression to the screen, but does not perform any conversions.

-T checks that the compressed file is correct. , but did not understand the pressure.

-U is similar to the-f parameter, but in addition to updating existing files, other files in the compressed file are extracted to the directory.

-V performs yes when the detailed information is displayed. or view the compressed files directory, but do not press.

-Z Displays only the memo text of the compressed file.

-A necessary character conversion for the text file.

-B Do not convert the text file to character.

The file names in the-C compressed file are case sensitive.

-J does not handle directory paths that are contained in compressed files.

-L Changes all the file names in the compressed file to lowercase.

-M sends the output to the more program processing.

-N Do not overwrite the original file when extracting.

-O do not need to ask the user first, unzip overwrite the original file after execution.

-p< password > password using zip option.

-Q does not display any information when executing.

-S converts white space characters in the file name to baseline characters.

-V retains the file version information for the VMS.

-X Unzip while the original uid/gid of the file is stored back.

[. zip file] Specifies a. zip compressed file.

[file] Specifies which files in the. zip archive to process.

-d< directory > Specifies the directory to be stored after the file has been decompressed.

-x< file > Specifies which files in the. zip archive are not processed.

-Z unzip-z equals execute zipinfo instruction.

Command name: Zip

Function Description: Compress the file.

Syntax: Zip [-acddffghjjkllmoqrstuvvwxyz$][-b < working directory >][-ll][-n < tail string >][-t < date time >][-< compression efficiency >][compressed file [Documents ...] [-i < template style;] [-x < template style;]

Note: Zip is a widely used compression program that compresses files that have a ". zip" extension.

Parameters

-A adjusts the executable auto-unzip file.

-b< working directory > Specifies the directory where files are temporarily stored.

-C adds a comment to each compressed file.

-d deletes the specified file from within the compressed file.

The directory name is not established within the-D compressed file.

-F The effect of this parameter is similar to specifying the "-u" parameter, but not only updates the existing file, and if some files do not already exist in the compressed file, use this parameter to add it to the compressed file.

-F attempt to repair a corrupted compressed file.

-G compresses the file after it is appended to the existing compressed file, rather than creating a new compressed file.

-H online Help.

-j saves only the file name and its contents, not any directory names.

-J Delete unnecessary data before compressing the file.

-K uses the file name in MS-DOS compatible format.

-L When compressing a file, replace the LF character with the LF+CR character.

-ll the LF+CR character into the LF character when compressing the file.

-L displays copyright information.

-M compresses the file and joins the compressed file, deletes the original file, and then moves the file to the compressed file.

-n< string > does not compress a file with a specific trailing string.

-O to compress files that have the most recent change time in the file, set the change time for the compressed file to be the same as the file.

-Q does not show the instruction execution process.

-R recursively handles all files and subdirectories under the specified directory.

-S contains the system and hidden files.

-t< Date Time > Set the date of the compressed file to the specified date.

-T checks that each file within the backup file is correct.

-U replace the newer file into the compressed file.

-V Displays the instruction execution process or displays version information.

-V Saves the file properties of the VMS operating system.

-W in the file name if the version number, this parameter is only valid under the VMS operating system.

-x< template style > exclude files that match the criteria when compressing.

-X does not save additional file attributes.

-Y saves the symbolic connection directly, not the file that the connection points to, and this parameter is only valid under systems such as UNIX.
