I have this script
#!/bin/sh
for i in `ls -R`
do
echo "Changing $i"
fromdos $i
done
I want to remove "^M" charcaters from many files which are in more subdirectories. I got this:
fromdos: Unable to access file
Is there somethig i'm missing?
Thanks in advance.
ls -R lists everything, including directories. So you're telling fromdos to act on actual directories is some cases.
Try something like this:
find . -type f -exec fromdos {} \;
I guess you don't need a for loop.
Here is a quick panorama of solutions for files with extension ".ext" (such commands shall be somehow restrictive)
note : ^M is obtained with CTRL-V" + "CTRL-M"
# PORTABLE SOLUTION
find /home -type f -name "*.ext" -exec sed -i -e 's/^M$//' {} \;
# GNU-sed
find /home -type f -name "*.ext" -exec sed -i -e "s/\x0D$//g" {} \;
# SED with more recent nux
find /home -type f -name "*.ext" -exec sed -i -e "s/\r$//g" {} \;
# DOS2UNIX
find /home -type f -name "*.ext" -print0 | while read -r -d "$(printf "\000")" -r path; do dos2unix $path $path"_new"; done
# AWK
find /home -type f -name "*.ext" -print0 | while read -r -d "$(printf "\000")" -r path; do awk '{ sub("\r$", ""); print }' $path > $path"_new"; done
# TR
find /home -type f -name "*.ext" -print0 | while read -r -d "$(printf "\000")" -r path; do cat $path | tr -d '\r' > $path"_new"; done
# PERL
find /home -type f -name "*.ext" -exec perl -pi -e 's/\r//g' {} \;

I am trying to move about 700,000 .jpg files from one directory to another in my Ubuntu server. I tried the following:
xargs mv * -t /var/www/html/
and
echo (*.jpg|*.png|*.bmp) | xargs mv -t /var/www/html/
and
echo (*.jpg) | xargs mv -t /var/www/html/
and
find . -name "*.jpg" -print0 | xargs mv * ../
and they all give me the same error: /usr/bin/xargs: Argument list too long
what should I do? Please help me out. Thanks :)
If you use find I would recommend you to use the -exec attribute. So your result should be find . -name "*.jpg" -exec mv {} /home/new/location \;.
However I would recommend to check what the find command returns you, replacing the exec part with: -exec ls -lrt {} \;
Try:
find /path/to/old-directory -type f | xargs -i mv "{}" /path/to/new-directory
You could have tried:
for f in *.jpg do;
mv -tv $f /var/www/html/
done
for f in *.png do;
mv -tv $f /var/www/html/
done
for f in *.bmp do;
mv -tv $f /var/www/html/
done
also, you should carefully read xargs(1); I strongly suspect that
find . -name "*.jpg" -print0 | xargs -n 1000 -I '{}' mv '{}' ../
should work for you
At last, learn more about rename(1). It is probably enough for the job.
Then i trying to use this script
for line in `cat dirs.txt`;
do
find "$line" -type f \( -name '*good*' -o -exec grep -F "badbad" {} \; \) -exec echo {} \;;
done
I get error on each existing dirs and match the find criteria
find: /home/goods/ : No such file or directory
find: /home/bads/ : No such file or directory
find: /home/fill/ : No such file or directory
But then i look manualy this dirs exist and i can read them all
Why this happens?
You must check in file for ^M$
You can do that with command cat dirs.txt -vET
Then you must trim them all with command cat dirs.txt|tr -d "\r" >1.txt
Issue is that you have dos (^M) line endings, in the file. Running dos2unix dirs.txt dirs.txt should solve the problem. Ideally, you also shouldn't use for line in $(cat ..., but something like
while IFS= read -r line; do
find "$line" -type f \( -name '*good*' -o -exec grep -F "badbad" {} \; \) -exec echo {} \;
done < dirs.txt
FreeBSD 9.2 RELEASE p2
I have a file fromdirs.txt. In this file is a new line separated directory list like so:
/etc
/home
/home/goods/
I need to first find in all directory's files which have names like "good" or contain string "(NODES_'TASK')" and then copy all these files into the directory /tmp.
2.sh file chmod +x and is 755
fromDirs.txt file chmod +x and is 755
This code give me error
IFS=$'\n' read -d '' -r -a dirs < fromDirs.txt
find "${dirs[#]}" -type f \( -name '*good*' -o -exec grep -F "(NODES_'TASK')" {} \; \) -exec cp {} /tmp/ \;
2.sh: cannot open fromDirs.txt : No such file or directory
2.sh: ${dirs[...}: Bad substitution
But File fromDirs.txt exist and 2.sh running from it allocation directory, also i trying to provide full path instead of fromDirs.txt and error the same
This code give me error
FILE=fromDirs.txt
IFS='\n'
while read -r dirs
do
find "$dirs" -type f \( -name '*good*' -o -exec grep -F "(NODES_'TASK')" {} \; \) -exec cp {} /tmp/ \;
done < "$FILE"
2.sh: 6: Syntax error: "done" unexpected (expecting "do")
This code give me error too
FILENAME=fromDirs.txt
awk '{kount++;print kount, $0}
END{print "\nTotal " kount " lines read"}' $FILENAME
2.sh: : not found awk: can't open file fromDirs.txt source line number 2
So how to read file line by line and do what i need?
This works for me
for line in "`cat fromDirs.txt`"; do find "$line" -type f \( -name '*good*' -o -exec grep -F "(NODES_'TASK')" {} \; \) -exec cp {} /tmp/ \;; done
How can I replace "abc" with "abcd" on all files of a folder using shell?
Is it possible using sed command?
Try the following command for the file file.txt:
sed -i 's/abc/abcd/g' file.txt
Try the following command for all files in the current folder:
find . -maxdepth 1 -type f -exec sed -i 's/abc/abcd/g' {} \;
For the files in the current directory and all subdirectories:
find . -type f -exec sed -i 's/abc/abcd/g' {} \;
Or if you are fan of xargs:
find . -type f | xargs -I {} sed -i 's/abc/abcd/g' {}
sed -i 's/abc/&d/g' *
should work.
Yes:
find /the/folder -type f -exec sed -i 's,\<abc\>,&d,g' {} \;
i have several php files, and there's references to .html files in those.
I need to replace ".html" to ".php"
how can i do this in bash ?
for file in $(find . -name "*.php"); do
sed "s/\.html/.php/g" $file > $$ && mv $$ $file
done
find -name '*.php' -exec sed -ie 's:.html:.php:g' {} \;
Try sed:
find -name "filenamepattern.php" -print0 | xargs -0 sed 's/\.html/\.php/g'
GNU find
find /path -type f -iname '*.php' -exec sed -i.bak 's/\.html/\.php/g' {} +;
