Top Forums Shell Programming and Scripting read line by line and create new file Post 302304994 by borobudur on Tuesday 7th of April 2009 05:30:01 PM

I solved it like this:
Code:
#!/bin/bash

# Reads from one file all lines
# takes the first word as the name of a new file
# creates the new file with that name
# adds text out of a file before and after

output='/path/to/output/dir'
input='/path/to/input/file.txt'
prefix='/path/to/input/start.txt'
sufix='/path/to/input/end.txt'

cd $output

awk '{print "" > $0".java"}' $input

for i in $( ls ); do
  cat $prefix >> $i
done

awk '{print $0 >> $0".java"}' $input

for i in $( ls ); do
  cat $sufix >> $i
done

Any suggestions of improvement?

GIT-CHECK-ATTR(1)						    Git Manual							 GIT-CHECK-ATTR(1)

NAME
git-check-attr - Display gitattributes information SYNOPSIS
git check-attr [-a | --all | attr...] [--] pathname... git check-attr --stdin [-z] [-a | --all | attr...] < <list-of-paths> DESCRIPTION
For every pathname, this command will list if each attribute is unspecified, set, or unset as a gitattribute on that pathname. OPTIONS
-a, --all List all attributes that are associated with the specified paths. If this option is used, then unspecified attributes will not be included in the output. --cached Consider .gitattributes in the index only, ignoring the working tree. --stdin Read file names from stdin instead of from the command-line. -z The output format is modified to be machine-parseable. If --stdin is also given, input paths are separated with a NUL character instead of a linefeed character. -- Interpret all preceding arguments as attributes and all following arguments as path names. If none of --stdin, --all, or -- is used, the first argument will be treated as an attribute and the rest of the arguments as pathnames. OUTPUT
The output is of the form: <path> COLON SP <attribute> COLON SP <info> LF unless -z is in effect, in which case NUL is used as delimiter: <path> NUL <attribute> NUL <info> NUL <path> is the path of a file being queried, <attribute> is an attribute being queried and <info> can be either: unspecified when the attribute is not defined for the path. unset when the attribute is defined as false. set when the attribute is defined as true. <value> when a value has been assigned to the attribute. Buffering happens as documented under the GIT_FLUSH option in git(1). The caller is responsible for avoiding deadlocks caused by overfilling an input buffer or reading from an empty output buffer. EXAMPLES
In the examples, the following .gitattributes file is used: *.java diff=java -crlf myAttr NoMyAttr.java !myAttr README caveat=unspecified o Listing a single attribute: $ git check-attr diff org/example/MyClass.java org/example/MyClass.java: diff: java o Listing multiple attributes for a file: $ git check-attr crlf diff myAttr -- org/example/MyClass.java org/example/MyClass.java: crlf: unset org/example/MyClass.java: diff: java org/example/MyClass.java: myAttr: set o Listing all attributes for a file: $ git check-attr --all -- org/example/MyClass.java org/example/MyClass.java: diff: java org/example/MyClass.java: myAttr: set o Listing an attribute for multiple files: $ git check-attr myAttr -- org/example/MyClass.java org/example/NoMyAttr.java org/example/MyClass.java: myAttr: set org/example/NoMyAttr.java: myAttr: unspecified o Not all values are equally unambiguous: $ git check-attr caveat README README: caveat: unspecified SEE ALSO
gitattributes(5). GIT
Part of the git(1) suite Git 1.8.5.3 01/14/2014 GIT-CHECK-ATTR(1)
