Parameter Expansion with regular expression
Hello experts,
I am exploring parameter expansion, and trying to cut the fields in a URL.
Following is the requirement:
I have
// abc.nnt /dir1/dir2/dir3/dir4/somefile.java
What i need to get is the path after dir3, and dir3 will be passed.
output that i need is dir4/somefile.java.
I am trying to use like
path="https://abc.com/dir1/dir2/dir3/dir4/somefile.java"
showseason=${path#https://abc.com/}
am getting /dir1/dir2/dir3/dir4/somefile.java as the output.
Please let me know how will the required output.
Thanks in advance.

Say you have this numeric variable that can be set by the user but you never want it to leave a certain range when it gets printed. How could you use parameter expansion such that it will never expand outside of that boundary? Thanks

raidfile-config
RAIDFILE-CONFIG(8) Box Backup RAIDFILE-CONFIG(8)
NAME
raidfile-config - Configure Box Backup's RAID files
SYNOPSIS
raidfile-config config-dir blocksize dir1 [dir2 [dir3]]
DESCRIPTION
raidfile-config creates a raidfile.conf file for Box Backup. This file holds information about the directories used to store backups in.
Box Backup supports userland RAID, in a restricted RAID5 configuration, where 3 and only 3 'drives' are supported. You can read more about
RAID5 (and other RAID-levels) here[1].
Parameters
The parameters are as follows:
config-dir
The directory path where configuration files are located. Usually this is /etc/box. raidfile.conf will be written in this directory.
blocksize
The block size used for file storage in the system, in bytes. Using a multiple of the file system block size is a good strategy.
Depending on the size of the files you will be backing up, this multiple varies. Of course it also depends on the native block size of
your file system.
dir1
The first directory in the built-in RAID array.
dir2
The second directory in the built-in RAID array. If you are not using the built-in RAID functionality, this field should be ignored.
You should not use the built-in RAID if you have a hardware RAID solution or if you're using another type of software RAID (like md on
Linux).
dir3
The third directory in the built-in RAID array. The same notes that apply to dir2 also apply to dir3.
Note that there are currently no way to add multiple disk sets to the raidfile.conf file using command line tools, etc. See
raidfile.conf(5) for details on adding more disks.
BUGS
If you find a bug in Box Backup, and you want to let us know about it, join the mailing list[2], and send a description of the problem
there.
To report a bug, give us at least the following information:
o The version of Box Backup you are running
o The platform you are running on (hardware and OS), for both client and server.
o If possible attach your config files (bbstored.conf, bbackupd.conf) to the bug report.
o Also attach any log file output that helps shed light on the problem you are seeing.
o And last but certainly not least, a description of what you are seeing, in as much detail as possible.
FILES
raidfile-config generates the raidfile.conf(5) file.
