i am working on below given shell script, I found the solution from line 1 to line line 20 mentioned below. i need the windows optional commands for remaining commands of linux. e.g. mcopy, mformat, mattrib, can i use these commands in windows and if not then what are the windows counterpart of these commands.
#!/bin/sh <--------------line 1
set -e
asm() {
nasm -o $2 $1
}
asm bios/dosbios.asm bios/dosbios.sys
asm boot/mboot.asm boot/mboot.bin
asm util/format.asm util/format.com
asm util/fdisk.asm util/fdisk.com
asm util/reboot.asm util/reboot.com

export MTOOLSRC=mtools.cfg
perl -e 'print chr(0xf6) x 2880 x 512' >
disk/newdos.tmp
<-------- line 20
mformat -m 0xf8 -v DOS a:
mcopy bios/dosbios.sys a:io.sys
mcopy msdos/msdos.sys a:

mattrib -a +s +h +r a:msdos.sys
dd status=none if=boot/boot.com of=disk/newdos.tmp
conv=notrunc
mv disk/newdos.tmp disk/newdos.img
my question is that can i use these commands in windows also, if not then what are the counterpart commands in windows.

I have an file , my file name is lookup.txt. Sometimes this file content is 100 lines , so everything scroll while printing. Thats why i like to print it on screen in 2 or more columns.
my bash doesnt support commands like pr or columns.Need to be in old fashion shell.
Content of lookup file is:
1-Top Scores
2-Last Scores
3-Username
4-Birthday
5-Last Meal today
6-Coronavirus in Italy
7-Lets Stay Home
8-Winner
9-Germany and Belgium
10-Alfa
11-Bravo
12-Charlie and delta
For printing in columns i use this command found here on stackoverflow:
cat lookup.txt | xargs printf '%-24s\n' | sed '$p;N;s/\n//;$p;N;s/\n//'
and this is the print in columns:
1-Top Scores 2-Last
Scores 3-Username 4-Birthday
5-Last Meal today
6-Coronavirus in Italy
7-Lets Stay Home
8-Winner 9-Germany and
Belgium 10-Alfa 11-Bravo
12-Charlie and delta
What i need is to let sed not split the words into different columns but just the line.
1-Top Scores 6-Coronavirus in Italy 11-Bravo
2-Last Scores 7-Lets Stay Home 12-Charlie and delta
3-Username 8-Winner
4-Birthday 9-Germany and Belgium
5-Last Meal today 10-Alfa
if the 3 columns are to width then x chars then print in 2 columns (this last is optional)
thanks in advance

Not claiming complete credit, you can modify this andlrc's answer on In bash how can I split a column in several column of fixed dimension to your requirement.
Instead of appending the columns with a whitespace, you can use sprintf() to custom print your column strings. Tested on GNU awk
awk '
BEGIN {
# Numbers of rows to print
n=5;
}
{
# Add to array with key = 0, 1, 2, 3, 4, 0, 1, 2, ..
l[(NR-1)%n] = sprintf("%s%-24s", l[(NR-1)%n], $0)
};
END {
# print the array
for (i = 0; i < length(l); i++) {
print l[i];
}
}
' file
Try this:
cat lookup.txt | tr '\n' '\0' | xargs -0 -n 2 printf '%-24s %-24s\n'
The tr command will convert newlines to nul chars.
Then we tell xargs to take nul-separated args and pass two at a time to the command.
I am trying to download some files with snakemake. The files (http://snpeff.sourceforge.net/SnpSift.html#dbNSFP) I would like to download are on a google site/drive and my usual wget approach does not work. I found a bash function that does the job (https://www.zachpfeffer.com/single-post/wget-a-Google-Drive-file):
function gdrive_download () { CONFIRM=$(wget --quiet --save-cookies /tmp/cookies.txt --keep-session-cookies --no-check-certificate "https://docs.google.com/uc?export=download&id=$1" -O- | sed -rn 's/.*confirm=([0-9A-Za-z_]+).*/\1\n/p') wget --load-cookies /tmp/cookies.txt "https://docs.google.com/uc?export=download&confirm=$CONFIRM&id=$1" -O $2 rm -rf /tmp/cookies.txt }
gdrive_download 120aPYqveqPx6jtssMEnLoqY0kCgVdR2fgMpb8FhFNHo test.txt
I have tested this function with my ids in a plain bash script and was able to download all the files. To add a bit to the complexity, I must use a workplace template, and incorporate the function into it.
rule dl:
params:
url = 'ftp://ftp.ncbi.nlm.nih.gov/pub/clinvar/vcf_{genome}/{afile}'
output:
'data/{genome}/{afile}'
params:
id1 = '0B7Ms5xMSFMYlOTV5RllpRjNHU2s',
f1 = 'dbNSFP.txt.gz'
shell:
"""CONFIRM=$(wget --quiet --save-cookies /tmp/cookies.txt --keep-session-cookies --no-check-certificate "https://docs.google.com/uc?export=download&id={{params.id1}}" -O- | sed -rn "s/.*confirm=([0-9A-Za-z_]+).*/\1\n/p") && wget --load-cookies /tmp/cookies.txt "https://docs.google.com/uc?export=download&confirm=$CONFIRM&id={{params.id1}}" -O {{params.f1}} && rm -rf /tmp/cookies.txt"""
#'wget -c {params.url} -O {output}'

run:

There are four downloadable files for which I have ids (I only show one in params), however I don't know how to call the bash functions as written by ZPfeffer for all the ids I have with snakemake. Additionally, when I run this script, there are several errors, the most pressing being
sed: -e expression #1, char 31: unterminated `s' command
I am far from a snakemake expert, any assistance on how to modify my script to a) call the functions with 4 different ids, b) remove the sed error, and c) verify whether this is the correct url format (currently url = 'https://docs.google.com/uc?export/{afile}) will be greatly appreciated.
You would want to use raw string literal so that snakemake doesn't escape special characters, such as backslash in sed command. For example (notice r in front of shell command):
rule foo:
shell:
r"sed d\s\"
You could use --printshellcmds or -p to see how exactly shell: commands get resolved by snakemake.
Here is how I "solved" it:
import pandas as pd
rule dl:
output:
'data/{genome}/{afile}'
shell:
"sh download_snpsift.sh"
rule checksum:
input:
i = 'data/{genome}/{afile}'
output:
o = temp('tmp/{genome}/{afile}.md5')
shell:
'md5sum {input} > {output}'
rule file_size:
input:
i = 'data/{genome}/{afile}'
output:
o = temp('tmp/{genome}/{afile}.size')
shell:
'du -csh --apparent-size {input} > {output}'
rule file_info:
"""md5 checksum and file size"""
input:
md5 = 'tmp/{genome}/{afile}.md5',
s = 'tmp/{genome}/{afile}.size'
output:
o = temp('tmp/{genome}/info/{afile}.csv')
run:
with open(input.md5) as f:
md5, fp = f.readline().strip().split()
with open(input.s) as f:
size = f.readline().split()[0]
with open(output.o, 'w') as fout:
print('filepath,size,md5', file=fout)
print(f"{fp},{size},{md5}", file=fout)
rule manifest:
input:
expand('tmp/{genome}/info/{suffix}.csv', genome=('GRCh37','GRCh38'), suffix=('dbNSFP.txt.gz', 'dbNSFP.txt.gz.tbi'))
output:
o = 'MANIFEST.csv'
run:
pd.concat([pd.read_csv(afile) for afile in input]).to_csv(output.o, index=False)
And here is the bash script.
function gdrive_download () {
CONFIRM=$(wget --quiet --save-cookies /tmp/cookies.txt --keep-session-cookies --no-check-certificate "https://docs.google.com/uc?export=download&id=$1" -O- | sed -rn 's/.*confirm=([0-9A-Za-z_]+).*/\1\n/p')
wget --load-cookies /tmp/cookies.txt "https://docs.google.com/uc?export=download&confirm=$CONFIRM&id=$1" -O $2
rm -rf /tmp/cookies.txt
}
gdrive_download 0B7Ms5xMSFMYlSTY5dDJjcHVRZ3M data/GRCh37/dbNSFP.txt.gz
gdrive_download 0B7Ms5xMSFMYlOTV5RllpRjNHU2s data/GRCh37/dbNSFP.txt.gz.tbi
gdrive_download 0B7Ms5xMSFMYlbTZodjlGUDZnTGc data/GRCh38/dbNSFP.txt.gz
gdrive_download 0B7Ms5xMSFMYlNVBJdFA5cFZRYkE data/GRCh38/dbNSFP.txt.gz.tbi
So I have this function, I want this function to run everything that It contains in itself at the same time. So far it isn't working, and according to other sources, this is how you do it. The function itself works if its not in parallel.
#!/bin/bash
foo () {
cd ${HOME}/sh/path/to/script/execute
for f in *.sh; do #goes to "execute" directory and executes all
#scripts the current directory "execute" basically run-parts without cron
cd ~/sh/path/to/script
while IFS= read -r l1 #Line 1 in master.txt
IFS= read -r l2 #Line 2 in master.txt
IFS= read -r l3 #Line 3 in master.txt
do
cd /dev/shm/arb
echo ${l1} > arg.txt & echo ${l2} > arg2.txt & echo ${l3} > arg3.txt
cd ${HOME}/sh/path/to/script/execute
bash -H ${f} #executes all scripts inside "execute" folder
cd ~/sh/path/to/script/here
./here.sh &
cd ~/sh/path/to/script &
done <master.txt
done
}
export -f foo
parallel ::: foo
Results in
#No result at all....., just buffers. htop doesn't acknowledge any
#processes, and when this runs its pretty taxing on the cores.
master.txt content
In case this is relevant:
apple_fruit
apple_veggie
veggie_fruit
#apple changes
pear_fruit
pear_veggie
veggie_fruit
#pear changes
cucumber_fruit
...
I'm very new to using parallel, and don't know how it works in advanced(and basic) situations so would the loops interfere? And if it does interfere, is there a workaround?
The result is probably going to be something like:
inner() {
script="$1"
parallel -N3 "'$script' {}; here.sh {}" :::: master.txt
}
export -f inner
parallel inner ::: ${HOME}/sh/path/to/script/execute/*.sh
This will call each of the scripts in ${HOME}/sh/path/to/script/execute/ (and here.sh) with 3 arguments from master.txt like this:
${HOME}/sh/path/to/script/execute/script1.sh apple_fruit apple_veggie veggie_fruit
You need to change the scripts so that:
They get the arguments from the command line (not from arg.txt, arg2.txt, arg3.txt).
They send their output to stdout
It seems that Xcode really sucks at coloring the shell script. For example, if you copy the following snippet into your Xcode, most of the whole chunk is colored red.

It would look like this.
Is there a way whereby I can fix the Xcode coloring issue?
What's confusing Xcode's syntax highlighting here is specifically the combination of heredocs (<<EOF) and escaped backticks (\`).
There's no way to fix it as-is, but, so long as there is no substituted content in the heredocs, you can use a quoted heredoc to remove the requirement for escaped backticks in the first place:
cat <<'stage_tpl3' > fslvbm2c
...
template_list=`cat ../template_list`
...
stage_tpl3
When the terminating label for a heredoc is enclosed in quotes, substitutions within the heredoc are disabled. It works the exact same way, and Xcode is able to highlight it more gracefully. (As a bonus, it's also easier to read and write the script without all the backslashes in the way!)
As an aside, note that it's conventional to always use the label "EOF" for heredocs. Some editors special-case this for syntax highlighting. It's also easier to spot than something specific to the document.
I have a BASH/shell script, running on Linux, but it sometimes has a problem getting the drive labels, using blkid.. blkid gets the drive labels nad UUIDs of the given drive.
Example of blkid output:
# blkid /dev/sda1
/dev/sda1: LABEL="Home" UUID="f1e5e82b-1c75-4fd7-8841-6ad766152dcf" TYPE="ext2"
The problem occurs when the drive label has a newline character... I have included the relevant function. The problem seems to be with the eval command.. Can someone help me?
blkid_name_generator() {
#Gather blkid output and filter out required device
if [ ! -f /tmp/blkid.txt ]; then
blkid -c /dev/null > /tmp/blkid.txt
fi
blkid_cleaner &
LABEL=""
LABEL1=""
eval $( cat /tmp/blkid.txt | grep "$#:" | cut --delimiter=" " -f 2- | sed -e 's/ /;/g')
LABEL1=${LABEL//;/ } # akita beta4 fix: remove newlines below
LABEL=`echo $LABEL1 | tr -d '\n'` # akita beta5 fix, remove newlines from drive label
#Generate drive label
[ "$LABEL" = "" ] && ONEDRVLABEL="$#\n \n " || ONEDRVLABEL="${LABEL}\n($#)\n "
echo "${LABEL}" and "${ONEDRVLABEL}"
}
blkid_name_generator /dev/sda1
Here's my bash snippet:

Hope this helps!
I don't see exactly what your script is intending to do (apart from the missing bits).
Here's what I came up with:
blkid | perl -ne 'print "$1\n" if m/LABEL="(.*?)"/o'
It will show this (on my system):
test^J123
WIN7VIRT
TEMP
Note how the newline in the label is depicted as ^J ? Viewing through a hex encoder shows that it is indeed a two-character combination 0x5e 0x4a
Hope you can get some further with that.
PS: 'proof' that the newline is in fact correctly in the volume label
tune2fs /dev/sdc1 -l

Thanks to this question... I could find a solution for another problem. Example (sda2 = ntfs partition):
blkid /dev/sda2
Segmentation Fault (core dump)
Hard to find troubleshooting guide for this issue (ubuntu based OS or any other)
The reason behind is a malformed LABEL in NTFS partition.
(of course, mal-formation we cant see, as newlines ;-)
Solution: Clear LABEL with GParted; then rewrite it or set a new LABEL.
