View 5 Replies View RelatedI am supposed to take some small files, and print them to a specific printer, such that the small files are concatenated into one file. The file name has to be included in the file that gets printed.
Should I be looking to concatenate the files into one file with the file names included, and then print them?
something like: -printfunction -printername < file*
So if I have a file with a list of files:
file.txt
file1.a
file2.b
file3.c
and I wanted to perform a script using a loop or recursively on each of those files, is there any way that I could do this?
I saw that xargs might be able to help me.
Here is sorta what I want to do:
Code:
#!/bin/bash
cat file.txt | xargs?? # Some commands to turn each line into a variable
for var in ${@}; do # Some way to get each of the files
# script on each file
I'm using Ubuntu minimal install (With no window manager). What is the quickest and easiest way to upload a file somewhere? Something like a script to pastebin would work.
View 2 Replies View RelatedI have a small script that uses the find command to look for a log file named: backup_log.txt. And then uses the first value in the log file as a variable in the script later on. However, say there are two or more of these log files located in different directories, how would I let the user choose which log file will be the one to use, and then make that (fullpathtofile) the value of the variable that will be used.

I'm just starting out with shell-scripting, but having a problem with making new text files with the touch or cat > commands.
What I've been doing is touch testfile1.txt
Also, I've tried cat > testfile1.txt (text)
Console reports "bash: text1.txt: No such file or directory. Consfusingly, it works fine in the home-directory. But if I move the file to where I want it, I can no longer view, edit, etc. it.
I want to modify a file like /etc/gdm/custom.conf from the shell or a script.
# GDM configuration storage
[xdmcp]
[debug]
[daemon]
AutomaticLoginEnable=true;
AutomaticLogin=username;
But the idea is that I can add a line to a section and it check if the section is defined, (add the definition if not), the property is defined, let it undefine (erase the line), (and delete the section header if there is no property defined), etc...
I didn't find anything except gconftool-2 but it do not explain how to modify other files. (there is a shema file there).
there isn't a program/script to achieve this, but can easyly be made for every config file, If someone do something like that, with a little database of which markup use each file, it could become really popular.
I'm relatively experienced with UNIX and Linux, but this has me thrown for quite a loop, and it seemed like such a simple question. How would I go about finding the newest file in a file system? I thought something like:
Code:
ls -ltr `find /usr -type f`
would work, but I seem to be exceeding the argument maximum for ls:
ksh: 0403-029 There is not enough memory available now
I thought something involving xargs might work, but I really suck with that command.

View 13 Replies View RelatedI have a Python script that I run which needs to execute under a special environment, so I would run the program like so from my working directory (~/project/src):
python manage.py shell
This opens up an interactive shell for me to start typing my own commands.I have another set of administrative activities that I would like to house in another directory (~/project/admin). The manage.py is really finicky about running from the working directory. So, to make this whole thing work, I made a script which starts off like so:
#!/usr/bin/python ../src/manage.py shell
There are a couple problems with this. The first is that it doesn't work:
/usr/bin/python: can't open file '"/../src/manage.py" shell': [Errno 2] No such file or directory
How do you specify multiple parameters to the interpreter?How do I change the working directory?
Just using shell scripting, how can I insert text into the middle of a file name. The file has a predictable pattern, let's say 3 letters and 3 numbers and I want to insert text in the middle of those 2 patterns. Say ABC123 is the file name. As a result, the file name should be ABC.blah.123
