print a file on a single line

echo $(cat file)
Example: you have a package.txt you want to install on a system. Instead of this: cat package.txt package1 package2 package3 You want it to cat out on one line so you can print "yum install package1 package2 package3"

  • Using sed to extract lines in a text file If you write bash scripts a lot, you are bound to run into a situation where you want to extract some lines from a file. Yesterday, I needed to extract the first line of a file, say named somefile.txt. cat somefile.txt Line 1 Line 2 Line 3 Line 4 This specific task can be easily done with this: head -1 somefile.txt Line 1 For a more complicated task, like extract the second to third lines of a file. head is inadequate. So, let's try extracting lines using sed: the stream editor. My first attempt uses the p sed command (for print): sed 1p somefile.txt Line 1 Line 1 Line 2 Line 3 Line 4 Note that it prints the whole file, with the first line printed twice. Why? The default output behavior is to print every line of the input file stream. The explicit 1p command just tells it to print the first line .... again. To fix it, you need to suppress the default output (using -n), making explicit prints the only way to print to default output. sed -n 1p somefile.txt Line 1 Alternatively, you can tell sed to delete all but the first line. sed '1!d' somefile.txt Line 1 '1!d' means if a line is not(!) the first line, delete. Note that the single quotes are necessary. Otherwise, the !d will bring back the last command you executed that starts with the letter d. To extract a range of lines, say lines 2 to 4, you can execute either of the following: sed -n 2,4p somefile.txt sed '2,4!d' somefile.txt Note that the comma specifies a range (from the line before the comma to the line after). What if the lines you want to extract are not in sequence, say lines 1 to 2, and line 4? sed -n -e 1,2p -e 4p somefile.txt Line 1 Line 2 Line 4 Show Sample Output

    sed -n -e 1186,1210p

  • This command is useful for separating a text file where all the words are in one line. Any group of spaces will be replaced with a single newline. Instead of one long line of tokens. You'll have a long list of tokens. One token per line.

    cat file.txt|perl -ne '$_=~s/\s+/\n/g; print $_;'

  • The exported TSV file of Google Adwords' first five columns are text, they usually should collapse into one cell, a multi-line text cell, but there is no guaranteed way to represent line-break within cells for .tsv file format, thus Google split it to 5 columns. The problem is, with 5 columns of text, there are hardly space to put additional fields while maintain printable output. This script collapses the first five columns of each row into one single multi-line text cell. new line character we use Line-Separator character (unicode U+2028), which is respected by gnumeric. It outputs a new .tsv file that opens in gnumeric.

    awk -F $'\t' '{printf $1 LS $2 LS $3 LS $4 LS $5; for (i = 7; i < NF; i++) printf $i "\t"; printf "\n";}' LS=`env printf '\u2028'` 'Ad report.tsv'
