i am using putty to connect to the linux server and i am using nano as my text editor to write a bash script.
this is my script:
echo "Please enter your Username"
read userName
userName= grep $USER /etc/passwd | cut -d: -f5
echo "Welcome " $userName | cat >> output.txt
the problem i have is that when i enter my username, the output (my real name) does not display in the output.txt. instead it displays in putty. so when i run my script in putty it shows the message to enter username and after i enter my username my real name appears below it. i want it to show in the output.txt

I've found that making a for loop does not work with files that contain a space in the name. Something to due with a bug that they call a "feature" that stops the first variable at the first whitespace.
Using a "while" loop is not exactly what i require either seeing as I want to be able to view each image in the directory on screen and tag it accordingly, before it jumps off to the next image, and I'm not sure how to add a pause to a while loop.
How do I make a Bash script and loop Variables handle files like "files that contain spaces.jpg"

View 14 Replies View RelatedUsing awk I pull the first field of a random line from my datafile.myvar1=`awk -F" " 'NR=='$randline' {printf "%s", $1}' myfileThis works fine. The problem is there will be empty lines at the end of the file. Rather than using awkto filter out blank lines I would like to figure this out first.So I test $myvar1 for a blank string after setting $randline to one that I know is blank:test -z "$myvar1" && echo "true" || echo "false"But, this returns "false"? So the string is not zero length. Why? It's a tab-separated file. Is awk storing the tab with the $1 field or something.This is where I get headache. I try to echo my variable to see what it looks like.
echo "$myvar1"
outputs: nothing
echo "My variable is [$myvar1]"
outputs: [y variable is [
Why is the closing bracket at the beginning? What character could be stored in $myvar1 that would do such a thing and how did it get there?

I need to add a feature such that instead of hardcoding the ip address .. it takes them from a list and makes new files for each ip address for logging.. And also when log files are completed , They should be compressed using tar. How should i go about adding both these.. This is my first bash script.
I have a script that reads part of a line, delimited between the first and second intended part by a colon. Then it "chops" the part after the colon, which are words offset by commas (counting them beforehand so as to catch every word in the string's second part), like this:
Code:
"COLORS.JPG:red,orange,yellow,green,"
(Returning)
red
[code]....
single script that parses/breaks both parts of a line like this "COLORS.JPG:red,orange,yellow,green;blue,indigo,violet," so that the two parts, separated into single words (or two and three words, sometimes with spaces) can be used as single-line annotations and written to JPEG files using Exiv2. So far, I haven't been able to come up with a script that does this without one part of the total string(usually that part after the colon) becoming the first word in the second array. In other words, I look for this:
KEYWORDS:
[ ]red
[ ]orange
[ ]yellow
[code]....
Or vice-versa (ie, the second array winds up as a single-line "member" of the first). I think it's because I'm using a single while read loop to read the text file in which the filenames and substrings happen to be. If there's some way of reading a file once and going back to the beginning to read it again in another while loop, I haven't found it.
I am struggling with Bash scripting at the moment (I can't seem how anyone can write scripts with this language!!!) I have a need at home to have a cron job execute daily to lookup my downloads.txt file, read each url (per line) and download content from that url. Then that entry needs to be removed (well I keep all urls in memory and clear the file afterwards). If an error occurred during the download process, then the url is written to a downloads.err file. I got all the above working except for properly reading the url from the text file without including newline characters. I am using the following to read:
while read url; do
--Do whatever here--
done < downloads.txt
How can I get it not to let the url variable have newline characters?
I am trying to remove everything before my string code...

My assessment is making a tree from a text file as follows: -reading a file line by line
-making a binary tree from it
- traverse by level the binary tree
- posting the traversal result to the same file without overwriting the text file- it is required to be append to the bottom of the text file (i have to do this in 4 languages: c#,PHP from Xampp,java, python)
i read the file with this script in java:
public class FileToStringArray {

Is it possible to pass arguments to a source file in a bash script? For example

How would you check for the passed arguments in funclib without getting confused with any arguments passed to the main script?
I'm new to bash scripting and I've searched around the forums and Internet for this but haven't had any luck. I've found similar things but not what I need. What I need to do is write a simple script that uses what the user inputs to locate and display where a file is. I would prefer to use locate instead of find since I know that the person I am writing this for has locate on her machine (my mom, who is just beginning with Linux).I'm writing the script to make things easier for her while she learns In this particular part of the script I would like to be able to have the script prompt to enter the file she is searching for, read the her input and then display for her where the file is. I realize it would in most cases be much simpler just to teach her how to use locate, but she is very impatient and this is just a part of the script I will be writing, but I can't figure out how to do this.

Im writing my first bash script. Its function is to move files to the trash can and write a log file in the same format that the system does to allow for file restoration. The problem is that in bash, everything works fine, but in the OpenBox window session, the files are named after the source directory, not the original name. Heres the script:
Code:
#!/bin/bash
# trash - Script to move file or folder to the trash can and create a log file
##### Functions #####
err_output () # Writes error message {
echo "$0: cannot stat `$1': No such file or directory"
echo "USAGE: $0 SOURCE DEST"
exit 1 } >&2
write_log_numbered ()
# Writes log entry for numbered files {
echo "[Trash Info]" > $HOME/.local/share/Trash/info/${FILE}.$max.trashinfo
echo "Path="$PWD >> $HOME/.local/share/Trash/info/${FILE}.$max.trashinfo
echo "DeletionDate="`date "+%Y-%m-%dT%H:%M:%S"` >> $HOME/.local/share/Trash/info/${FILE}.$max.trashinfo
}
write_log_unique () # Writes log entry for unique files {
echo "[Trash Info]" > $HOME/.local/share/Trash/info/${FILE}.trashinfo
echo "Path="$PWD >> $HOME/.local/share/Trash/info/${FILE}.trashinfo
echo "DeletionDate="`date "+%Y-%m-%dT%H:%M:%S"` >> $HOME/.local/share/Trash/info/${FILE}.trashinfo
} make_paths () # Makes necessary folders {
mkdir -p ~/.local/share/Trash
mkdir -p ~/.local/share/Trash/files
mkdir -p ~/.local/share/Trash/info
}
##### Main #####
make_paths
SOURCE="$1"
DEST=$(dirname ~/.local/share/Trash/files/filename)
[ -e "$SOURCE" ] || err_output "$SOURCE"
[ -d "$DEST" ] || err_output "$DEST"
FILE="$(basename "$SOURCE")"
if [ -e "${DEST}/${FILE}" ]; then
max=0 DIR="$(pwd)" cd "$DEST"
shopt -s nullglob for backup in "${FILE}."; do
nr=${backup#${FILE}.}
if [[ "$nr" =~ ^[0-9]+$ ]]; then
if (( nr>max )); then
max="$nr" fi
fi
done
cd "$DIR"
max=$(( max + 1 ))
write_log_numbered
mv -- "$SOURCE" "${DEST}/${FILE}.$max"
else
write_log_unique
mv -- "$SOURCE" "$DEST/${FILE}"
fi
So I run the script with the test file "Junk". In bash, it moves over and its named correctly.
Code:
~/.local/share/Trash/files$ ls
file file.1 Files Files.1 Junk
The log file is also named correctly
Code:
~/.local/share/Trash/info$ ls
file.1.trashinfo Files.1.trashinfo Files.trashinfo file.trashinfo Junk.trashinfo
But, when I go to view the trash can in the file manager in Openbox, the file is called "Testing" which is the name of the source directory. However, if I go to the trashcan via its full path (going to .local/, then share/) all the files are named correctly. Whats going on here? Is there some way to get the trash can to read the correct file name?
