I'm trying to write a bash script to find all lines containing two different strings in many files. I don't have access to egrep so I want to use sed for this purpose.
The files will look like this:
FileX
------
Info:18
Data:76
Contact:me@home.com
Start:1500
I want to generate a new file from these files with only the rows containing Data and Start. Something like this:
for y in `ls /file*.db`;
do sed '/Data|Start/p' $y > newfile
done

I want to remove duplicate or multiple similar lines from multiple files. I.e. if I have four files file1.txt file2.txt file3.txt and file4.txt and would like to find and remove similar lines from all these files keeping only one line from these similar lines. I only that uniq can be used to remove similar lines from a sorted file.

fakeFile's contents :
Code:
blah $(date +%F) blah
fakeScript's contents :
Code:
while read line; do
echo $line
done < "fakeFile"
so here's the problem : is there any way to evaluate the fakeFile's contents (in the fakeScript), so that the term "$(date +%F)" (or any other bash script) in a string , translates to it's corresponding value ? (in this example , we want to have "blah current date" instead of " blah $(bash script) blah " )

I'm not overly great with bash scripting. I do more batch file stuff for Windows than anything else but I'm trying to branch out a bit. (Frankly, I'd love to do this in Ruby but I'm not there yet...) Maybe I'm not using the correct terminology and that's why my searches are coming up useless...
Anyway, I have a script that does some work with HandBrake. Although it deals with HandBrake, I think the issue is not with HandBrake itself. The issue: I had a simpler script which worked fine but it would give me an MP4 with a file name of: Some Movie Name.iso.mp4 and it would still play but I wanted to get rid of the .iso in the file name. I also wanted to drop it into another directory during the encoding. That's why you see a $source & a $destination variable.
handbrake.sh
Code:
#!/bin/bash
source=/media/data/movies
destination=/media/data/movies/mp4s

I've been surfing and searching the net quit a while now to make my own script, but I haven't been really successful ever since I want to make a script which can remove strings from my mp3 collection (file names).
For example:
Code:
101-bob_sinclar_feat_sean_paul-tik_tok_(radio_edit).mp3 --> bob_sinclar_feat_sean_paul-tik_tok_(radio_edit).mp3
10-Young Jeezy-Lose My Mind (78 Bpm) (Repack).mp3 --> young_jeezy-lose_my_mind.mp3
Now the problem is how can I remove the strings like:
101 & 10 (dynamic)
(%%% Bpm) (dynamic)
(Repack) (static)

I have multiple strings (eg. say two, firstLIST=(0 1 2) and secondLIST=(2 3)) and want to create a single string composed of their unique sorted elements. For the sample strings above, I'd like to build masterLIST=(0 1 2 3).I suppose I could write the elements of firstLIST and secondLIST to files
Code:
echo ${firstLIST[@]} > firstFILE
echo ${secondLIST[@]} > secondFILE
then use
Code:
sort firstFILE secondFILE | uniq > masterFILE
as this gives me a file populated with the elements I'm after, but I'm not sure how to read the elements back into masterLIST... and it doesn't seem "right" to create files to accomplish this. Is there a way to do this by manipulating the strings ${firstLIST[@]} and ${secondLIST[@]} directly? The closest I've come (not close at all) is
Code:
masterLIST=${firstLIST[@]}" "${secondLIST[@]}
but masterLIST built this way has only one element
Code:
$echo ${masterLIST[@]}
0 1 2 2 3
$echo ${#masterLIST[@]}
1
and I don't have access to the individual digits to then try to figure out how to remove duplicates.

...and returning the index of the found element in its array.
I have:
for ((i=0; i < ${#array1[@]}; i++)); do
# Read each line of the file test
if [[ $(eval "sed -n '$(($i+1))'p test") == *${array2[0]}* ]]
stuff
I want to find the index of the found substring in array2 and only if it isn't found, move on to the next element of array2. I don't know the size of array2 so that [0] has just got to go.

got the same thing in terms of a u: number but the issue is I need to remove duplicates and just leave one and the file has multiple duplicates of different u: numbers and it's 14,000 lines long. can anyone tell me if I can use awk? sed? or sort for something like this to? removing lines that have a certain string in there that's a duplicate.

I would like to find all the files that contains the strings I'm searching.
For example (it's just an example), I would like to search all the files in "/etc" that contains "eth0" and "us", whatever where are located those 2 strings, the important is that the 2 strings are in the files listed.
It would be something like a "grep -lr 'eth0' *" and "grep -lr 'us' *" but in one time/command, so that I don't have to make a comparison of the 2 list of files resulting from the 2 "grep" commands given higher.

I use udhcp with some of my minimal installs. I've messed around with the code a bit when it wasn't working correctly - a few years ago. I will find time - I hope soonish - to figure out how to do a few other things with it.
For now though, I'm using this string to grab my ip after startup
Code: Select allsu -c 'ifconfig eth0&&ifdown -a&&ifup lo&&ifup eth0'&&/sbin/ifconfig eth0
I realize I could substitute ifup -a but I'm more interested in figuring out how to make ifup wait for the ip to become available if it is not available yet.
Never mind that one, just typing out the question answered it for me, when I find it in the scripting man ' ; : " & =
Or if there are any other suggestions for better construction of the string.

I have a directory of orchestral music .ogg files from a family member. Each track is from a different artist and the CDDB entry adds a ":" character after the artist name in the track title.
Here is an example of what I am referring to:
Code: Select all13_-_Mozart:_Sonata_in_A_major_KV_331.ogg
I would like to parse file names in any given directory and search for the string Code: Select all: and replace it with Code: Select all_ According to this post on stackoverflow, I can use Perl to accomplish this task. I've tried Code: Select allperl -i.bak -pe 's/:/_/' but since I am still learning Perl I'm probably commiting a PEBKAC error.
How would I go about solving this issue with regular expressions using Perl?

I'm trying to search for several strings, which I have in a .txt file line by line, on another file.
So the idea is, take input.txt and search for each line in that file in another file, let's call it rules.txt.
So far, I've been able to do this, to search for individual strings:
Code: Select allimport re
shakes = open("output.csv", "r")
for line in shakes:
if re.match("STRING", line):
print line,
How can I change this to input the strings to be searched from another file?
So far I haven't been able to.

I am reading the output of /proc/acpi/thermal_zone/ATF0/temperature in a program to read my CPU temp. I am using cat like the following:
Code:
#cat /proc/acpi/thermal_zone/ATF0/temperature
temperature: 49 C
I basically want to get rid of the spaces in between temperature and the actual temperature. Is there a command I can pipe the cat output to, to remove the spaces. I have seen suggestions for sed, or tr, but for some reason I cannot get them to work properly.

I'm trying to search through some pdf files and I'm doing so by converting them to text files using pdftotext which is fine but I'm trying to get the number of occurrences in a paragraph of different words and it's adding a new line character at what it thinks is the right hand margin. I'm trying to remove all these singe new line characters but keep the doubles and I can't seem to work it out. i.e.
This is some text that has been broken.
Another paragraph.

I have a script that calls for a file description on a core file. I then pull the name of the process that caused the core file.
unfortunately, the process name is pulled with a leading ' amd a tailing'. I would like to remove the leading char and the last char.
code:
VAR=`file /tmp/core.1432 | awk '{ print $14}'`
echo "Process Name: $VAR"
output:
Process Name: 'ProcessName'
Results I need:
Process Name: ProcessName
I tried sed, but it seems to not like using the special char '.

However, the ffmpeg command generates a temporary file blahblah.mpg.tmp of about 1GB per hour of transcoded video.My issue is that I can't seem to delete these files automatically from any bash script.Now from the command line, I can cd to the directory and just rm -f *.tmp and they get deleted. However, from my script, that same command doesn't remove those files. I thought maybe the file was in use, so I put a sleep command in for like an hour before the delete happens, but it still fails. I also put rm -f /mnt/mythtv/*.tmp in a root cronjob and it still doesn't delete the files.
If I just rm *.tmp I do get a prompt about "Are you sure you want to delete this write protected file?". But the -f switch seems to work fine as a normal user from the command line and just delete them.Does anyone have an idea how to troubleshoot this problem? The particular filesystem that the tmp files get generated on is on it's own xfs partition mounted as /mnt/mythtv.

I want to delete all files within a specific folder without actually deleting the folder, what is a good bash command for this?. I found this one but encountered some errors even though I am executing it within the specific folder:
useratdebian:/home/user/folder# find . -type f -exec rm -rf {} ;
[1] 5052
useratdebian:/home/user/folder# find: missing argument to `-exec'
[1]+ Exit 1 find . -type f -exec rm -rf
The command as it appears is:
find . -type f -exec rm -rf {} ;
how to delete only the files contained within the folder called "folder" for example?

An app failed to load properly and now i'm stuck in a sequence I don;t understand the solution for.
sudo apt-get autoremove
dpkg was interupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
