Bash scripting does my head in. I have searched for regex assignment, but not really finding answers I understand. I have files in a directory. I need to loop through the files and check if they fit certain criteria. File names under a certain sequence need to have their sequence increased. Those over a certain sequence need to trigger ...
Is there any way to change the following string so I don't get any problems when there are files/folders with spaces in them? files=`find ~/$folder -name "*@*" -type f` I'd prefer if there was a solution that wouldn't have to involve having to change other parts of my code but this line of code, as everything seems to be working corre...

I've gotten it working until the remote MYSQL database...

I can determine filetype in linux using "file" command. Does somebody have bash script for it? For example: Initial dir contains files: 001, 002, 003, 004. A...

I also need to do this in parallel but I am having some trouble with how the output is being sent into the log file. I would like the output to look like: host | hostTo | result of ping command but since I have this running as a back...
How can I join all of the files in a directory. I can do it in one step by explicitly naming the files below, is there a way to do it without explicitly naming the files? join <(\ join <(\ join <(\ join\ <(sort ${rpkmDir}/HS0477.chsn.rpkm)\ <(sort ${rpkmDir}/HS0428.chsn.rpkm) )\ <(sort ${rpkmDir}/HS0419.chsn.rpkm) )\ <(sort ${rpkmDir}/...

Major bash-noob here. Writing my second program again. For my homework, I need to write a number of grep statements using regexps. This is the first one I'm trying to write. I'm saving it as grep.bash: #!/bin/bash egrep bright_side_of_life 'the' The error I get is : egrep: the: no such file or directory ...
One of my homework questions is to search using grep an lines that contain the word 'death' or 'breath'. I know the [] operator acts as an or, but how do I use it to specify 'd' or 'br' ? This won't work: egrep [dbr]eath test_file ...
Tried to set some aliases in my .bashrc file. This one... export alias umusic="/Volumes/180 gram/Uncompressed/" ...gets the following error... -bash: cd: /Volumes/180: No such file or directory ...when I try "cd $umusic". I've tried various methods of escaping that whitespace in the directory name, to no avail. (180\ gram, 180%...
I have a bash script that runs on a machine (called lazyguy) that is usually turned off. Every night, lazyguy wakes up at a known time programmed in the BIOS, does a bunch of processing and inserts data to its Postgres database. Then, it goes to sleep (database and all). How can get notified when the script did NOT run? Ideally, I'd ...
I'm just trying my hand in bash, so I wrote a simple program in C to count the number of characters in a file. This is my C program: #include <stdio.h> int main() { int i, nc; nc = 0; i = getchar(); while (i!=EOF){ nc = nc + 1; i = getchar(); } printf("%d\n",nc); return 0; } This is the bash command I'm using ...
Hi all ! (Sorry for the confusion. Previous $ sign occurred when I tried to simplify the actual problem. Thanks for correcting the question) I wanted to split a directory name on underscores (ex: dir_to_split="my_test_dir") like this: my_dir=($dir_to_split) var=$(echo $my_dir | awk -F"_" '{print $1,$2,$3}') set -- $var splited_1=...
Question: is there a simple sh/bash/zsh/fish/... command to print the absolute path of whichever file I feed it? Usage case: I'm in directory /a/b and I'd like to print the full path to file c on the command-line so that I can easily paste it into another program: /a/b/c. Simple, yet a little program to do this could probably save me 5 ...
I have written the following two functions in Bash: function prepend_path() { PATH=$1:$PATH } function prepend_manpath() { MANPATH=$1:$MANPATH } The bodies of the functions are actually going to be more complicated. To avoid code duplication, I would like to do something like the following: function prepend() { "$1"=$2:"$1" } functio...
hi the following script.bin append by tee lines to file.log (from my bash script) IP=xxx.xxx.xxx.xxx ./script.bin | tee -a file.log my target is to add the "IP=127.0.0.1" after each line that created by tee (the IP address is example) remark: we can't modify the script.bin in order to add the "IP=127.0.0.1" -because its binary...
