Unix write file

I am looking to do a ls on a folder and have the output of the ls be structured so that is is modificaiton date, file name with the date in a format that is compatible with mysql. I am trying to build a table that stores the last modification date of certain files so I can display it on some web Need to develop a unix shell script for the below requirement and I need your assistance: 1 search for file.

Need help in writing a script to create a new text file with specific data from existing two files. Hi, I have two text files. Need to create a third text file extracting specific data from first two existing files.. Writing a text to many files. Is there a command in shell-script that I can use that copies a string or writes it to many files?

Say I have files a, b and c and I want to copy or write the text "Hallo, I am a newbie! I know I can do echo "Hallo, I am a newbie! I don't know how to do it in shell script Picking out text from one file and writing it to another. I have one file that is a collection of discarded emails. Each email is it's own section with each section beginning with the same header ie 'Another Email'. Sed creates or truncates the given filename before reads the first input line and it writes all the matches to a file without closing and re-opening the file.

Sed reads a line and place it in a pattern buffer and writes the pattern buffer to the given output file according to the supplied commands. Thanks in advance…. I have a scenario like, Needs to content between 2 strings Begin and End ,after End i have some more lines i also needs to print next 4 lines from End. I would lie if you can correct following shell.

I prefer flexible , user can give the line numbers from and to , for selection from a file. With due Regards. The easiest way for a beginner to modify file or directory permissions is to use the symbolic mode.

With symbolic permissions you can add, delete, or specify the permission set you want by using the operators in the following table. Here's an example using testfile. The second way to modify permissions with the chmod command is to use a number to specify each set of permissions for the file. Each permission is assigned a value, as the following table shows, and the total of each set of permissions provides a number for that set.

Here's an example using the testfile. All the permissions mentioned above are also assigned based on the Owner and the Groups. The value of the user can be either the name of a user on the system or the user id uid of a user on the system.

The chgrp command changes the group ownership of a file. The value of group can be the name of a group on the system or the group ID GID of a group on the system. Often when a command is executed, it will have to be executed with special privileges in order to accomplish its task.
