Linux下的压缩解压缩

zip

The following examples illustrate typical uses of the command zip for packaging a set of files into an “archive” file, also called “zip file”. The command uses the standard zip file format. The archive files can therefore be used to tranfer files and directories between commonly used operating systems.[1]

zip -r myfile.zip ./*
# archive all the files and folders in current directory
# into myfile.zip -r is short for recurse

zip -d myfile.zip smart.txt
# delete smart.txt from myfile.zip

zip -m myfile.zip ./rpm_info.txt
# add rpm_info.txt into myfile.zip

zip -r filename.zip file1 file2 file3 /usr/work/school 
# archive file1 file2 file3 and  /usr/work/school into filename.zip
